In a prior sample of u. s. adults, the center for disease control (cdc), found that 8% of the people in this sample had pinworm but the margin of error for the population estimate was too large. they want an estimate that is in error by no more than 2.5 percentage points at the 95% confidence level. enter your answers as whole numbers.

(a) what is the minimum sample size required to obtain this type of accuracy? use the prior sample proportion in your calculation. the minimum sample size is 1 u. s. adults.

(b) what is the minimum sample size required to obtain this type of accuracy when you assume no prior knowledge of the sample proportion? the minimum sample size is 2 u. s. adults.

a) 453  b) 1537

Step-by-step explanation:

As per given , we have

Margin of error : E= 0.025

Critical value for 95% confidence interval :

a) The prior estimate of population proportion : p=0.08

Required sample size :-

The minimum sample size is 453 U.S. adults.

b) Since the prior estimate of population proportion is not available , so we take p= 0.5

Required sample size :-

The minimum sample size is 1537 U.S. adults.

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.

step-by-step explanation: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.

.632

step-by-step explanation:

6 * 1/10 = 3/5

3*0.01 = 0.03

3/5 + 0.03 = .63

2*0.002 = .002

.63 + 0.002 = .632
