Question

The average American walks 3000 steps per day. A researcher believes that, due to the pandemic, people are walking less. A survey of 51 individuals found that the average number of steps they walked per day was 2903, with a standard deviation of 501 steps. At the level of significance, test the researcher’s hypothesis. You may use StatCrunch

Set up the null and alternative hypotheses:

Is the test Left-tail Right-tail Two-tailed
Is the sample size large enough to continue? Explain.

Calculate the test statistic using the formula or obtain it from StatCrunch (2 decimals):

Sketch a picture of what the p-value means, using the test statistic

Find the p-value __________________ (Use StatCrunch)

Make your decision Reject Fail to Reject
