Question 11. Which IAT data set are you working with?2.3.Use StatCrunch and your unique IAT sample to estimate the mean age for the population of IAT participants at the90% confidence level. Copy the contents of your StatCrunch output window and paste them into your response. (Noneed to type anything here - just copy and paste the contents of your StatCrunch output window.)Are conditions met to estimate the mean age for the population of IAT participants? (Be sure to support your answeras demonstrated throughout Unit 8.)4.State the confidence interval, and then interpret the confidence interval in context.5.What is the margin of error (MOE)?6.Which would be more accurate, the 90% confidence interval you found or an 85% confidence interval?

Report an appropriate hypothesis test for a positive linear relationship and use a 5% significance level. Explain the potential error in words, in context. In the answer options below I have used the phrase “a certain relationship” because I don’t want to give away exactly what type of relationship it is. Group of answer choices We would be accepting that there was a certain relationship between Sale amount and Tip when actually there wasn’t. We would not be accepting that there was a certain relationship between Sale amount and Tip when indeed there wasn’t.

Women stereotypically talk more than men do and researchers wondered how much more. Suppose a study attempted to determine the difference in the mean number of words spoken by men or women per day. The results of the study are summarized in the table.

First, determine the positive critical value, ?, for a 95% confidence interval to estimate how many more words women speak each day on average compared to men, ?w−?m. Give your answer precise to at least three decimal places. Determine lower and upper limits of a 95% confidence interval for how many more words speak each day on average compared to men. A negative number would indicate how many fewer words women speak each day on average…

K Do freshmen spend significantly more time on social media than other class ranks? A recent study investigated the amount of time per day freshmen, sophomores, juniors, and seniors spent on social media while doing schoolwork. The students surveyed were U.S. residents from a 4-year, public, primarily residential institution. The accompanying computer output shows the mean time each cohort spent on social media and an ANOVA table. Construct a 95% confidence interval to compare the population mean time spent per day on social media between freshmen and seniors. Click the icon to view the summary statistics and ANOVA table.
