Step-by-step explanation:
A store manager claims that 60% of shoppers who enter her store make a purchase. To investigate this claim, she selects a random sample of 40 customers and finds that 40% of them make a purchase. She wants to know if the data provide convincing evidence that the true proportion of all customers who enter her store that will make a purchase differs from 60%. The P-value of this test is 0.0098. Interpret the P-value.
Assuming the true population proportion of shoppers who will make a purchase is 0.60, the probability of obtaining a sample statistic of 0.40 in a random sample of 40 customers is 0.0098.
Assuming the true population proportion of shoppers who will make a purchase differs from 0.60, the probability of obtaining a sample statistic of 0.40 in a random sample of 40 customers is 0.0098.
Assuming the true population proportion of shoppers who will make a purchase is 0.60, the probability of obtaining a sample statistic as extreme as or more extreme than 0.40 in a random sample of 40 customers is 0.0098.
Assuming the true population proportion of shoppers who will make a purchase is different from 0.60, the probability of obtaining a sample statistic as extreme as or more extreme than 0.40 in a random sample of 40 customers is 0.0098.
Answer:
I do believe that it is Option B
(Assuming the true population proportion of shoppers who will make a purchase differs from 0.60, the probability of obtaining a sample statistic of 0.40 in a random sample of 40 customers is 0.0098.)
Step-by-step explanation:
This sample provide evidence that the grocery store manager overstated the true proportion P-value = 0.0333.
What is p-value?In null-hypothesis significance testing, the p-value is the probability of obtaining test results at least as extreme as the result actually observed, under the assumption that the null hypothesis is correct.
here, we have,
Given data in the question:
To test whether population proportion p is overstated;
Null hypothesis H₀ : p = (75%) = 0.75
Alternative hypothesis H₁ : = < (75%) < 0.75
Now, sample proportion p" = 64 / 100 = 0.64
From the dot plot below,
we will determine the p-value for test { P(p" < 0.64)}
The number of times p"<0.64 in 150 simulations is 5
Therefore:
P(p" < 0.64 ) = 5 / 150 = 0.0333
P-value = 0.0333
At 5% level of significance;
0.0333 < 0.05
Therefore, we reject null hypothesis H₀ at 5% level of significance,

complete question:
A grocery store manager claims that 75% of shoppers purchase bananas as least once a month. Technology was used to simulate choosing 150 SRSs of size n = 100 from a population of shoppers where 75% buy bananas. The dotplot shows pˆ = the sample proportion of shoppers who bought bananas in the past month. A random sample of 100 shoppers from the store were selected and 64 bought bananas in the past month. Does this sample provide evidence that the grocery store manager overstated the true proportion? Justify your answer.

Tyrone completed 3/8 of a report on Wednesday. Then he completed 1/2 of the report on Thursday. Did Tyrone complete more of his report on Wednesday or Thursday? Explain
Answer:
tyrone completed more of his report on Thursday.
Step-by-step explanation:
first you have to find the common denominator. in this case it would be 8. then you have to multiply 1/2 times 4 to make the denominators equal. so now instead of 1/2 it is 4/8. and 3/8 < 4/8

In a five-day work week, there are about 100 cans that are dented in the factory
Answer:
AThe factory can expect to have an average of 50 cans dented each day they are produced at the factory.
Step-by-step explanation:
1/20 of 1000 is 50
so A is your answer
The factory can expect to have an average of 50 cans dented each day they are produced at the factory.
What is the probability?Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.
There are 1000 cans of cat food produced daily at a factory.
In the meeting last week, the company stated that of the cans produced daily there is a probability of 1/20 of being dented.
The number of cans of cat food the company expects to be dented is given by;
[tex]\rm = Total \ number \ of \ can \ produced \ daily \times Denied \ can\\\\=1000\times \dfrac{1}{20}\\\\=50[/tex]
Hence, the factory can expect to have an average of 50 cans dented each day they are produced at the factory.

The value of y for the given circle will be 54°.
What is a circle?A circle is a geometrical figure which becomes by plotting a point around a fixed point by keeping a constant distance.
The diameter is the longest line that can be drawn inside a circle.
In our daily life, we always see circle objects for example our bike wheel.
Area of circle = πr² and the perimeter of circle = 2πr where r is the radius of the circle.
In the given question by the circle theorem that if a curve makes a 2x angle then the extreme point will make the angle on circle as x.
So angle y = half of angle 108°
∠Y = 108°/2 = 54°

The equation of a parabola is y=x2–8x+14. Write the equation in vertex form.
Answer:
Step-by-step explanation:
y=x^2-8x+14
To write in vertex form, group the two x-terms to make a complete square, adjust the constant term accordingly
y = x^2-8x+16 -2
factor the first three terms on the right hand side
y = (x-4)^2 -2
This means that the vertex is at x-4 = 0, or x=4, and y=2.

U(1, 3)
From midpoint to U:
(x, y) → (x - 2, y + 1)
To get from midpoint to V, we inverse the formula:
(x, y) → (x - 2, y + 1)
(x, y) → (x + 2, y - 1)

4(x-3)^2 = 80
4x-12^2= 80 --- (distribute)
4x+144= 80 --- ( why a positive 144 because a (-) * a (-) = a (+)
4x = (80-144) --- ( subtract -144 from +144(do it on both sides)
4x = -64 --- (divide both sides by 4)
x= -16
Answer:
2√5 +3
Step-by-step explanation:
Isolate x:
4(x-3)^2 = 80
Divide both sides by 4.
(x-3)^2 = 20
Then take the square root of each side.
(x-3) = √20
Add 3 to each side.
x = √20 + 3
√20 can be rewritten as 2√5.
x = 2√5 + 3

If 20 percent of the animals are amphibians and yiu are trying to find the total amound of numbers in the zoo you first have to realize that 20% is equal to 1/5. Then since you are trying to find the total and not decrease the number, you get the reciprical of 1\5, which is 5/1 and multiply it by 65/1 . 5 × 65 equals 325.

The model represents an inequality. what is the solution set for the inequality?
Answer:
Then the solution set is all the values of x equal to or larger than -3.
Step-by-step explanation:
First, we know that each long strip represents an x.
Each white square represents 1.
Each grey square represents -1
Then, at the left side, we have:
8 long stripes.
12 white squares
Then we can write that as:
8*x + 12*1 ≥
And in the right side, we have 12 grey squares, then that is:
≥ 12*-1 = -12
Then the inequality is:
8*x + 12 ≥ -12
To find the solution set, we just need to isolate x.
First, we can subtract 12 in both sides to get:
8*x + 12 - 12 ≥ -12 - 12
8*x ≥ -24
Now we can divide both sides by 8
8*x/8 ≥ -24/8
x ≥ -3
Then the solution set is all the values of x equal to or larger than -3.
