An eCommerce website displays the content slightly differently depending on the device used to access the website. Suppose the website manager knows that the proportion of customers who access the website using a smartphone is 0.62.
The website manager wants to collect a sample such that the standard deviation of the sample proportion is less than 0.02. What is the minimum sample size required to satisfy this criterion?
Note:
1- Round any intermediate numbers to 4 decimal places.
2- Round your final answer to the nearest integer.

An eCommerce website displays the content slightly differently depending on the device used to access the website. Suppose the website manager knows that the proportion of customers who access the website using a smartphone is 0.58. The website manager wants to collect a sample such that the standard deviation of the sample proportion is less than 0.04. What is the minimum sample size required to satisfy this criterion?
According to recent studies, cholesterol levels in healthy adults average about 215 mg/dL with a standard deviation of about 28 mg/dL and are roughly normally distributed.
Suppose we collect a random sample of 39 healthy adults and measure their cholesterol level. What is the standard deviation of the distribution of sample average (sampe size 39)?Note:1- Round any intermediate numbers to 3 decimal places.2- Round your final answer to 3 decimal places. Enter your final answer with 3 decimal places.

a. An analyst from an energy research institute in California wishes to estimate the 95% confidence interval for the average price of unleaded gasoline in the state. In particular, she does not want the sample mean to deviate from the population mean by more than $0.06. What is the minimum number of gas stations that she should include in her sample if she uses the standard deviation estimate of $0.35, as reported in the popular press? Round intermediate calculations to...

A manager wants to compare the mean time required to build a product using two different assembly methods, A and B. The time per unit was recorded for independent random samples from each method. The results are below. Assuming that the variances for the two populations are equal, use this data to form a 99% confidence interval for the true difference (μA−μB)(μA−μB) between the mean times for the two methods. Do not round intermediate calculations. Enter your final answers as...
