Can you please assist me in determining the degrees of freedom without rounding as well (alpha value of .05). Also, I am needing assistance with what the critical value is and if we fail to reject the null hypothesis or not. Thank you.
Use the calculator displays to the right to make a decision to reject or fail to reject the null hypothesis at a significance level of a = 0.05.

The displays provided from the technology available below result from using data for a smartphone carrier's data speeds at airports to test the claim that they are from a population having a mean less than 6.00 Mbps. Conduct the hypothesis test using these results. Use a 0.05 significance level. Identify the null and alternative hypotheses, test statistics, and P-value, and state the final conclusion that addresses the original claim.

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 to he test statistic in order to find the p-value. Then, make a conclusion based on those results.
