LIO WII Sdve us response. 807) Question 1 Question 1 8 points It calc भनाई Use this formula as needed: U-12 o + n n2 A researcher tested two new exercise routines, PowerHour, and MightyFifty on reducing heart rate. For Power Hour, each participant performs a routine consisting of 50 each of jum jacks, push-ups, and sit ups in two 30-minute sessions every week for 6 weeks. With the MightyFifty, the participants perform the same routine but only for a total of 50 minutes each At the end of the six week period, he measured the heart rate of the participants. At the beginning, the mean of participants' heart rate was 71.5. At the end of the study, the mean of 6 participants in the Power Hour program was 69.5 with variance of 2.1, while that of 5 participants in the Mighty-Fifty program was 68.9 with standard deviation of 1.5. The researcher concluded that the MightyFifty Program is significantly better in lowering the heart rate than the Power Hour Program. Is his claim true? Answer by first completing the calculation of each of the following and then explaining the t-value obtained! Copy the following and paste in your answer box for answers to the calculation questions below. Include your calculation in your answer! T-ral
t-calc = df = T-crit t value is < =, or > t-critical Is the researcher's conclusion is correct? Is the MightyFifty Program significantly better than the PowerHour Program in lowering the heart rate ? Explain why or why not! Make sure to Include Your Calculation for each question below. A. Calculate t calc by answering the following: a. Calculate the numerator, or |H1-H2). Submit your answer as a = 2 2 01 + ni . (You may mention "square root of" for the sign. Submit your answer as b b. Calculate the denominator, or, n2 C. What is your t value? Submit as t-calc B. Calculate the degree of freedom for the two sets of data. Submit your answer as df = C. Using the chart below, determine if the t value is < =, or > t-critical
a. Calculate the numerator, or H1 - H2l. submit your answer as a = b. Calculate the denominator, or 0,2 02 + (You may mention "square root of" for the sign. Submit your answer as b ni M2 C. What is your t value? Submit as t-calc = B. Calculate the degree of freedom for the two sets of data. Submit your answer as df = C. Using the chart below, determine if the t value is < =, or > t-critical Table 10-3. Critical values of "1" d.1. significance level p=0.05 12.706 significance level p=0.01 1 63.657 2 4.303 9.925 3 3.182 5.841 4 2.776 4.604 5 2.571 4.032 6 2.447 3.707 3.499 7 2.365 8 2.306 3.355 9 2.262 3.250 10 2.228 3.169 11 2.201 3.106 Submit your answer as -> the t-calc is and it is (<,, or >) (select one) compared to the t-critical value hich is D. Based on your t-value results in (C), determine if the researcher's conclusion is correct! Is MightyFifty better man Power Hour
