An automobile manufacturer would like to know what proportion of its customers are dissatisfied with the service received from their local dealer. The customer relations department will survey a random sample of customers and compute a 95% confidence interval for the proportion that are dissatisfied. From past studies, they believe that this proportion will be about 0.28. Find the sample size needed if the margin of error of the confidence interval is to be no more than 0.02. (Round your answer up to the nearest whole number.)

Answers

Answer:

The sample size needed if the margin of error of the confidence interval is to be no more than 0.02.

n= 2015

Step-by-step explanation:

Given the customer relations department will survey a random sample of customers and compute a 95% confidence interval for the proportion that are dissatisfied

Given data from  past studies, they believe that this proportion will be about 0.28

The proportion of success(p)  = 0.28

We know that the margin of error of 95% of intervals of given proportion

margin of error =  (2√(p(1-p) )/(√(n) )…(i)

Given margin of error = 0.02

Substitute values in equation (i) cross multiplication √n

0.02 √n  = 2√0.28X0.72

On calculation, we get √n = 44.89

squaring on both sides, we get

n = 2015

Conclusion:-

The sample size needed if the margin of error of the confidence interval is to be no more than 0.02.

n= 2015

Coopers & Lybrand surveyed 210 chief executives of fast-growing small companies. Only 51% of these executives had a management succession plan in place. A spokesperson for Cooper & Lybrand said that many companies do not worry about management succession unless it is an immediate problem. However, the unexpected exit of a corporate leader can disrupt and unfocus a company for long enough to cause it to lose its momentum. Use the data given to compute a 92% confidence interval to estimate the proportion of all fast-growing small companies that have a management succession plan.

Answers

Answer:

92% Of confidence intervals to estimate the proportion of all fast-growing small companies that have a management succession plan.

(0.46154 , 0.558)

Step-by-step explanation:

Given sample size 'n' = 210

The sample proportion 'p' = 51% = 0.51

Confidence intervals are determined by

(p^(-) - z_(\alpha ) \sqrt{(p^(-) (1-p^(-) )/(n) } , p^(-) +Z_(\alpha ) \sqrt{(p^(-) (1-p^(-) ))/(n ) } )

The 92% of z-score value

Z_{(\alpha )/(2) } = Z_{(0.08)/(2) } = Z_(0.04) = 1.405

92% Of confidence intervals to estimate the proportion of all fast-growing small companies that have a management succession plan.

(0.51 - 1.405 \sqrt{(0.51 (1-0.51 )/(210) } , 0.51 +1.405 \sqrt{(0.51 (1-0.51))/(210 ) } )

on calculation , we get

(0.51-0.048 , 0.51 + 0.048)

(0.46154 , 0.558)

Final answer:-

92% Of confidence intervals to estimate the proportion of all fast-growing small companies that have a management succession plan.

(0.46154 , 0.558)
