A sample of 56 randomly selected cellphones of a new model were checked for a particular defect. Of these, 38 of the cellphones were found to be defective. Find a 80% confidence interval for p. Use the Agresti-Coull method.

Answers

Answer:

Confidence Interval: (0.60, 0.76)

Step-by-step explanation:

The provided information is:

Sample Size (n) = 56

Consider X be the number of defective cellphones. Then X = 38

Proportion of defective cellphones is: $p=(38)/(56)=0.68$

At 80% confidence interval, value of z is 1.28

Thus, the 80% confidence interval for proportion is given as:

$p\pm z\sqrt{(p(1-p))/(n)}}\n=0.68\pm1.28\sqrt{(0.68*0.32)/(56)}\n=(0.60,0.76)$

Which strategies can be used to solve this problem? Rosa organized a game day at her house. She plans to have 2 groups of 5 people play charades, and 3 groups of 4 people play board games. What is the greatest number of people who could be at Rosa's game day?

Choose all answers that are correct.

A.
Draw a diagram.
Draw 2 squares and 5 circles. Then draw 3 squares and 4 circles. Add the total number of squares and circles.

B.
Use logical reasoning.
Think that finding 2 groups of 5 is the same as 2 × 5 = 10 and that 3 groups of 4 is the same as 3 × 4 = 12. Then add 10 + 12.

C.
Model the problem.
Show 2 groups of 5 chips and 3 groups of 4 chips. Then count all the chips.

D.
Translate into an equation.
2 × 3 × 4 × 5 = n
