As the population standard deviation σis known, and the sample size is also greater than 30, we will assume that the distribution follows normal. We will use z test because the value of population standard deviation σis known. The value of zα/2for 95% confidence level is 1.96, which can be obtained by using the standard normal table.Hence, the correct option is B. zα/2=1.96

Use the t-distribution to find a confidence interval for a difference in means y, - M, given the relevant sample results. Give the best estimate for 41 - M2, the margin of error, and the confidence interval. Assume the results come from random samples from populations that are approximately normally distributed. A 99% confidence interval for My - A using the sample results x1 = 546, S, = 117, m, = 340 and X2 = 451,52 = 90, M2 = 200 Enter the exact answer for the best estimate and round your answers for the margin of error and the confidence interval to two decimal places. Best estimate = Margin of error = Confidence interval

You recently sent out a survey to determine if the percentage of adults who use social media has changed from 62%, which was the percentage of adults who used social media five years ago. Of the 2283 people who responded to survey, 1635 stated that they currently use social media.a) Use the data from this survey to construct a 94% confidence interval estimate of the proportion of adults who use social media. Record the result below in the form of (#,#)(#,#). Round your final answer to four decimal places.
If n=27, (x-bar)=46, and s=19, construct a confidence interval at a 99% confidence level. Assume the data came from a normally distributed population. Give your answers to one decimal place. <μ<
A sample of 32 people were randomly selected from among the workers in a shoe factory. The time taken for each person to polish a finished shoe was measured. The sample mean was 3.10 minutes. Assume σ = 0.94 minutes. Construct a 90% confidence interval for the true mean time, µ, to polish a shoe. Write down which table and critical value you used. Make sure you round your interval numbers correctly and circle your answer.
