How Much Do You Read? ~ A nation-wide survey conducted in 2019 asked a random sample of US adults, "During the past 12 months, about how many books did you read either all or part of the way through? Please include any print, electronic, or audiobooks you may have read or listened to." The survey results reported the mean number of books read to be 15. 39 Kelly is a library science major and wonders if adults who have a library card report reading more books in a year than the nationally reported mean.

What is the test statistic? ? = Kelly calculates a p-value of 0.046187. Which of the following are correct interpretations of the p-value? Select all that apply: A. A p-value of 0.046187 means that there is a 4.6187% chance that the null model is a good fit for the observed data. B. Under the null model, we would expect a sample mean of 16.7 or more approximately 4.6187% of the time in repeated sampling. C. A p-value of 0.046187 means we have strong evidence that null hypothesis is true. D. A p-value of 0.046187 means we have strong evidence against the null hypothesis. Calculate the effect size for Kelly's hypothesis test. â = Kelly shares her ideas with two friends in her major, Manuel and Josie, who decide to conduct similar hypothesis tests with samples from their own ometown libraries. Manuel obtains a sample size of 15, a p-value of 0.151 and an effect size of 0.69. Josie obtains a sample size of 44, a p-value of 0.0034 and an effect size of 0.7. Josie's results ? ✓Manuel's results because the ? ✓are ?
