Expert Solution

We have given here,

x=135
n=190
Estimate for sample proportion

Level of significance is =1-0.90=0.1
Z critical value(using Z table)=1.645

A sociologist wants to construct a 90% confidence interval for the proportion of children aged 8-10 living in New York who own a cell phone. A survey by the National Consumers League taken in 2012 estimates the nationwide proportion to be 0.41. Using this estimate, what sample size is needed so that the confidence interval will have a margin of error of 0.02?

In each case, find the approximate sample size required to construct a 90% confidence interval for p that has sampling error SE=0.07. a. Assume that p is near 0.4. b. Assume that you have no prior knowledge about p, but you wish to be certain that your sample is large enough to achieve the specified accuracy for the estimate. a. The approximate sample size is _____ b. The approximate sample size is _____

Determine an approximate sample size required to construct a 90% confidence interval for the mean number of miles on four-year -old Honda Civics, with a margin of error of 1000 miles. Assume that a preliminary study showed that the standard deviation is estimated to be 19,700 miles. A random sample of 32 washing machines had a mean replacement time of 10.6 years and a population standard deviation of 2.1 years. Find the margin of error that corresponds to 99% confidence...
