Using the information obtained from a study on heart rate, the following data were obtained for the hypothesis test:• A doctor is testing the claim that the average heart rate of patients is less than 70 bpm.• Assume the significance level is a = 0.05.• The z- test statistic is calculated as -2.01.What is the p-value and conclusion for this hypothesis test?Move the blue dot to choose the appropriate test (left-, right, or two-tailed). Use the graph below to move the slider tohe test statistic in order to find the p-value. Then, make a conclusion based on those results.

It is given that the claim is that the average heart rate of patients is less than 70 bpm.

Only 15% of registered voters voted in the last election. Will voter participation increase for the upcoming election? Of the 347 randomly selected registered voters surveyed, 56 of them will vote in the upcoming election. What can be concluded at the a = 0.01 level of significance? a. For this study, we should use z-test for a population proportion b. The null and alternative hypotheses would be: Họ: ? Select an answer (please enter a decimal) H.: ?vSelect an answer v (Please enter a decimal) c. The test statistic ?v (please show your answer to 4 decimal places.) d. The p-value = (Please show your answer to 4 decimal places.) e. The p-value is v f. Based on this, we should fail to reject g. Thus, the final conclusion is that ... O The data suggest the population proportion is not significantly higher than 15% at a = 0.01, so there is statistically significant evidence to conclude that the percentage of registered voters who will vote in the upcoming election will be equal to 15%. a…
A data set includes data from student evaluations of courses. The summary statistics are n=95, x=3.32, s=0.64.
