In a statistics activity, students are asked to determine if there is a difference in the proportion of times that a spinning penny will land with tails up, and the proportion of times a spinning dime will land tails up. The students are instructed to spin the penny and the dime 30 times and record the number of times they land tails up. For one student, the penny lands tails side up 18 times, and the dime lands tails side up 20 times.
Based on the 98% confidence interval, (–0.36, 0.22), is there evidence of a difference in proportions of tails side up for a penny and a dime?
There is convincing evidence because the two sample proportions are different.
There is not convincing evidence because the interval contains 0.
There is not convincing evidence because the interval contains both negative and positive values for the true difference.
Answer: B) There is not convincing evidence because the interval contains 0.
==============================================================
Explanation:
The 98% confidence interval (-0.36, 0.22) means we are 98% confident that the difference of proportions p1-p2 is somewhere between those two endpoints of -0.36 and 0.22 Values in this interval are possible values of p1-p2.
Note how 0 is in this interval. So it's possible that p1 - p2 = 0. Because of this, we fail to reject the null hypothesis. The null in this case is that p1 - p2 = 0 which can be restated as p1 = p2. The null is the assumption that the two population proportions (p1 and p2) are the same.
The alternative hypothesis is that p1-p2 is not zero. If we got a confidence interval like (0.22, 0.55), this example doesn't have 0 in the interval, then that would mean we reject the null since its unlikely that p1-p2 is equal to zero.
----------------
In short,
If the confidence interval contains 0, then you fail to reject the nullIf the confidence interval doesn't contain 0, then you reject the null.In this case, we fail to reject the null and we don't have enough evidence to show that p1 = p2 is false. So for now, we assume it's true.

Step-by-step explanation:
Ethan has $620 to spend at a bicycle store for some new gear and biking outfits. Assume all prices listed include tax. He buys a new bicycle for $427.57. He buys 4 bicycle reflectors for $11.38 each and a pair of bike gloves for $31.41. He plans to spend some or all of the money he has left to buy new biking outfits for $57.75 each. Write and solve an inequality which can be used to determine oo, the number of outfits Ethan can purchase while staying within his budget.
Answer: 620≥ 427.57+ 11.38(4)+ (31.41) +57.75x
Step-by-step explanation:
So our limit is the 620$ that he has to spend. We know for a fact that the bike costs about 427.57 dollars. 4 $11.38 reflectors are purchased as well as gloves for 31.41. Now however many outfits he can purchase cannot exceed or go over his money limit of 620 so the variable (x) represents how many outfits he can buy without going over.
We are required to write an inequality for the problem and also solve it
The number of biking outfit Ethan can purchase is 2
Given:
Total amount Ethan has = $620
Amount of bicycle = $427.57
Bicycle reflector = $11.38
Cost of 4 Bicycle reflector = $11.38 × 4
= $45.52
Cost of bike glove = $31.41
Cost of biking outfit = $57.75
Write an inequality to solve for the number of biking outfit Ethan can purchase
let
x = number of biking outfit Ethan can purchase
620 ≥ 427.57 + 45.52 + 31.41 + 57.75x
620 ≥ 504.5 + 57.75x
620 - 504.5 ≥ 57.75x
115.5 ≥ 57.75x
x ≥ 115.5 / 57.75
x ≥ 2

Aaron is having rain gutters installed around the perimeter of his roof. How much will he spend if he is charged $3.50 per foot?
Answer:
$294.35
Step-by-step explanation:
left and right side of the house: 15 ft + 15 ft = 30 ft
top part of the house: (20 ft - 12 ft = 8 ft) 8ft + 9.6 ft + 7.5 ft = 25.1
bottom part of the house: (20 ft - 15 ft = 5 ft) 15 ft + 5 ft + 4. 5 ft + 4.5 ft = 29
30ft + 25.1ft + 29ft = 84.1
84.1 ft x $3.50 = 294.35

The tuition for a state resident to attend a particular state college is $8000 this year. The tuition is expected to increase 6.25% per year for the next 5 years. Write an equation to represent the situation.
Answer:
8,000^0.0625=5
Step-by-step explanation:
Lol I was doing my homework rn and I wasn't 100% sure of my answer so I looked it up on brainly. So an exponential equation should look like this e^a=b so with the three values $8,000 , 6.25% , and 5 years I kind of just mixed around the numbers a bit in the exponential equation till one worked. So yeah...
Answer:
f(t)=8000e^(0.0625)(5)
Step-by-step explanation:
exponential growth function is f(t)=Pe^(rt)
where P is starting value, or price
e is the e on you calculator
r is rate of increase, in this case 6.25/100 is 0.0625, which is the rate
t is the time given

A triangular pane of glass has a height of 42 inches and an area of 336 square inches. What is the length of
the base of the pane?
PLEASE HELP IM BEGGING
Answer:
its 16
Step-by-step explanation:
area for a triangle is 1/2 the base times the height.
IN order to find out the base you need to multiply the area by two and then divide by 42 to find the base. X will represent the base
so
336 *2 = 42x
672= 42x
672/42=x
16 = x
Answer: 16
Step-by-step explanation:
X^2+ 14x = -33
Quadratic equation
x=-3
x=-11
because
x(x+14)=-33
so if x = -11 it will be 3*-11
and if x= -3 it will be -3*11
Answer:
x = -3, -11
Step-by-step explanation:
First, factor
Get all the terms on one side by adding 33 to both sides:
[tex]x^2 + 14x + 33 = 0[/tex]
now, you want to find two numbers that add up to 14 and multiply to 33.
those numbers would be 3 and 11.
so you can then make it:
[tex](x + 3)(x+11)=0[/tex]
you know that either x + 3 or x + 11 = 0,
so you can say:
x + 3 = 0
x = -3
ork
x + 11 = 0
x = -11
so x = -3, -11.

What is perimeter of the semi circle?
Answer:
54.22 mm
Step-by-step explanation:
Find the circumference of the circle and then divide it by 2.
We start with the formula for the circumference for the circle:
C = 2πr
To find r, divide 22 by 2:
22/2=11
Now find the cicumference:
C = 2πr = 2(3.14)(11) = 108.46 mm
NOW, to find the perimeter of the semicircle, divide the circumference by 2:
108.46/2 = 54.22 mm
Let g(x) be the reflection across the x-axis of the function f(x) = 7x + 3. Identify the rule for g(x).
Answer:
(x,y) => (x, -y)
Step-by-step explanation:
[tex]y = 7x + 3[/tex]
[tex] - y = 7x + 3[/tex]
[tex]y = - 7x - 3[/tex]
so
[tex]g(x) = - 7x - 3[/tex]
Hence, [tex]g(x) = - 7x - 3[/tex].
What is the function?
Functions are often defined by a formula that describes a combination of arithmetic operations and previously defined functions; such a formula allows computing the value of the function from the value of any element of the domain.
Here given that,
Let [tex]g(x)[/tex] be the reflection across the x-axis of the function [tex]f(x) = 7x + 3[/tex]. Identify the rule for [tex]g(x)[/tex].
So,
[tex]y = 7x + 3\\-y= 7x + 3\\y = - 7x - 3\\g(x)=- 7x - 3[/tex]
Hence, [tex]g(x) = - 7x - 3[/tex].
