Seven television sets are chosen at random (i.e without replacement) from a shipment of 240 television sets of which 15 are defective. Calculate the probability that at least 1 of the chosen televisions are defective
Answers
Answer:
7/16
Step-by-step explanation:
Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.
For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one ids attached to the event. If it doesn't a value of zero is attached to the event.
Proportion of defective televisions in the shipment = 15/240 = 1/16
Probability that 1 of the 7 chosen is defective = 1/16 x 7 = 7/16

Answer:
A) 10π ft; 25π ft²
B) 12π ft; 36π ft²
Step-by-step explanation:
The circumference is given by ...
C = πd = 2πr . . . . . . . . . . for radius r or diameter d
The area is given by ...
A = πr² = (π/4)d²
__
A) For a diameter of 10 ft, the circumference is π(10 ft) = 10π ft.
The area is (π/4)(10 ft)² = 25π ft².
__
B) For a radius of 6 ft, the circumference is 2π(6 ft) = 12π ft.
The area is π(6 ft)² = 36π ft².

A lumber company is making boards that are 2578.0 millimeters tall. If the boards are too long they must be trimmed, and if they are too short they cannot be used. A sample of 20 boards is made, and it is found that they have a mean of 2580.2 millimeters with a variance of 64.00. Is there evidence at the 0.1 level that the boards are either too long or too short?

Answers
Answer:
⅛
Step-by-step explanation:
Each mark (x) on the plot presents the distance that each student jumped.
There are 24 marks there, so it means there is a total of 24 students whose distance jumped were recorded.
Number of students that jumped 5½ ft = 3
Fraction of the students that jumped 5½ ft = no of students that jumped 5½ ft / total number of students
= 3/24

Alice is buying a
bicycle that regularly
cost $120. It is on
sale for 25% off and
the tax rate is 9.125%.
is the final amount cheaper or more expensive than the original price?
Answers
Answer:
NO
the final amount is 98.21 which is less than 120
Step-by-step explanation:
Price after discount = $120 x (100 - 25%)
$120 x 0.75 = $90
tax = $90 x 0.09125 = $8,21
final amount = $90 + 8.21 = 98.21

There is concern that increased industrialization may be increasing the mineral content of river water. Ten years ago, the silicon content of the water in a certain river was 5 mg/L. Eighty-five water samples taken recently from the river have mean silicon content 5.4 mg/L and standard deviation 1.2 mg/L. a. Find the P-value. b. Do you believe it is plausible that the silicon content of the water is no greater than it was 10 years ago
Answers
Answer:
a) P value = 0.0013
b) No, it is not plausible that the silicon content of the water is no greater than it was 10 years ago
Step-by-step explanation:
The null hypothesis here is “Mean is equal to 5” while alternate hypothesis is that “Mean is greater than 5”
Given
Mean = 5, x’ = 5.4 and sigma = 1.2 and n = 85
Z = x-u’/sigma/sqrt n
Substituting the given values, we get –
Z = 3.02
A) P value = 0.0013 which is less than 0.05 and thus we will reject the null hypothesis
B) There is enough evidence to reject the null hypothesis
