Use technology to find the​ P-value for the hypothesis test described below.   The claim is that for a smartphone​ carrier's data speeds at​ airports, the mean is μ=16.00 Mbps. The sample size is n=19 and the test statistic is t=1.224.

The claim is that weights (grams) of pennies made after 1983 have a mean equal to 2.500 g as required by mint specifications. The sample size is n = 37 and the test statistic ist = -0.331. Find the P value. Answer: The P value is (Round to four decimal places.)

In a study, a random sample of 20 adults rated the effectiveness of advertisements. Each adult rated an advertisement that lasted 30 or 60 seconds. The block design in the accompanying table shows these ratings (on a scale of 1 to 5, with 5 being extremely effective). Use a = 0.05 and a technology tool and the given block design to perform a two-way ANOVA test. Click the icon to view the block design and ratings. Determine the null and alternative hypotheses for the main effects. Select all that apply. O A. Ho: The length of the ad has no effect on the rating. B. Ho: The rating has no effect on the advertising medium. Ha: The rating has an effect on the advertising medium. Ha: The length of the ad has an effect on the rating. O c. Ho: The advertising medium has no effect on the rating. D. Ho: : The advertising medium has no effect on the length of the ad. Ha: The advertising medium has an effect on the rating. : The advertising medium has an effect on the length of the ad. Ha: length…

Use the random sample data to test the claim that the mean travel distance to work in California is less than 35 miles. Use 1% level of significance. Sample data:   x¯=32.4 mis=8.3 min=35   Identify the tail of the test. Find the P-value        Will the null hypothesis be rejected?        Is the initial claim supported?

Reading Program Summer reading programs are very popular with children. At the Citizens Library, Team Ramona read an average of 23.2 books with a standard deviation of 5.8. There were 16 members on this team. Team Beezus read an average of 26.1 books with a standard deviation of 4.0. There were 23 members on this team. Did the variances of the two teams differ? Use =α0.05. Use the traditional method of hypothesis testing and let σ1 be the standard deviation for Team Ramona. Assume that all variables are normally distributed. State the hypotheses and identify the claim. H0:  Claim or not a Claim H1:  Claim or not a claim This Hypothesis test is a one-tailed or two-tailed test. Find the Critical Value(s):  Compute the test Value: Make the decision: Summarize the results.

Use the pulse rates in beats per minute​ (bpm) of a random sample of adult females listed in the data set available below to test the claim that the mean is less than 69bpm. Use a 0.05 significance level. Determine the p-value, test statistic, and whether to reject or support the null hypothesis.  Pulse Rates (bpm)4758945542428462993656838640967652866179101964387103596043524566974010140833853398649613552933856446594

Historically, the percentage of U.S. residents who support stricter gun control laws has been 55%. A recent Gallup Poll of 2500 people showed 1723 in favor of stricter gun control laws . Assume the poll was given to a random sample of people. QUESTION Test the claim that the proportion of those favoring stricter gun control has changed from 0.55. Perform a hypothesis test, using a significance level of 0.01. What kind of test will you need to perform?  A right, one-tailed z-test A left, one-tailed z-test A two-tailed z- test
