If the sample correlation coefficient in Q1 above, were to be 0.85. Which choice provides the best conclusion of a hypothesis test: HO: p=0 vs HA: p70 using a=0.05. Reject HO since t stat > t critical value (5.398 > 2.306) None of these choices are correct. Reject HO since t stat > t critical value (3.952 > 2.447) Do Not Reject HO since t stat > t critical value (3.952 > 2.447)

JMP Pro 15 preferred but Excel is okay.

Consider the following hypothesis test. Ho: µ1 – µ2 = 0 Ha: µ1 – µ2 0 The following results are for two independent samples taken from two populations. Excel File: data10-03.xlsx Sample 1 Sample 2 n1 = 80 n2 = 70 = 104 T2 = 106 %3D 01 = = 8.4 02 = 7.6 Enter negative values as negative numbers. a. What is the value of the test statistic? (to 2 decimals) b. What is the p-value? (to 4 decimals) c. With a = 0.05, what is your hypothesis testing conclusion? - Select your answer -

You wish to test the following claim (HaHa) at a significance level of α=0.02α=0.02.      Ho:p1=p2       Ha:p1≠p2The 1st population's sample has 150 successes and a sample size = 751. The 2nd population's sample has 114 successes and a sample size = 500. What is the test statistic (z-score) for this sample? (Round to 3 decimal places.) test statistic = What is the p-value for this sample? (Round to 3 decimal places.) p-value = The p-value is... greater than αα less than (or equal to) αα This test statistic leads to a decision to... reject the null fail to reject the null accept the null Correct As such, the final conclusion is that... There is not sufficient sample evidence to support the alternate hypothesis claim that p1 is not equal to p2. The sample data support the alternate hypothesis claim that p1 is not equal to p2.

Select the appropriate null and alternative hypothesis for the following research question: Does a different proportion of people enjoy playing video games compared to those who enjoy playing sports? phat1 = proportion of people who enjoy playing video games more than sports phat2 = proportion of people who enjoy playing sports more than video games A. Null Hypothesis: People enjoy playing video games less than or equal to playing sports i.e. phat1 <= phat2   Alternative Hypothesis: People enjoy playing video games more than playing sports i.e. phat1 > phat2 B. Null Hypothesis: People enjoy playing video games a different amount than playing sports i.e. phat1 =/= phat2   Alternative Hypothesis: People enjoy playing video games the same as playing sports i.e. phat1 = phat2 C. Null Hypothesis: People enjoy playing video games the same as playing sports i.e. phat1 = phat2   Alternative Hypothesis: People enjoy playing video games a different amount than playing sports…

This chart shows the results of two random samples that measured the average number of minutes per charge for AA Lithium-ion (Li-ion) rechargeable batteries versus Nickel-Metal Hydride (NiMH) rechargeable batteries. Down below shows the hypothesis test using significance level (α) = 0.05 to determine if the true average number of minutes per charge for NiMH batteries is smaller than that for Li-ion batteries.     1. From the data given from the first graph below, what would be the correct p value? (the one tail or the two tail?)   t-Test: Two-Sample Assuming Unequal Variances                 NiMH Li-ion   Mean 89.35714 95   Variance 3.93956 59.75   Observations 14 17   Hypothesized Mean Difference 0     df 19     t Stat -2.89621     P(T<=t) one-tail 0.004628     t Critical one-tail 1.729133     P(T<=t) two-tail 0.009255     t Critical two-tail 2.093024     For the bottom graph: 1..

Q4) Suppose that when data from an experiment was analyzed, the P-value for testing Ho: u = 100 versus Ha: µ < 100 was calculated as 0.047. At the 0.01 significance level, Họ would

You wish to test the following claim (HaHa) at a significance level of α=0.02α=0.02.      Ho:p=0.72Ho:p=0.72      Ha:p>0.72Ha:p>0.72You obtain a sample of size n=403n=403 in which there are 316 successful observations.What is the test statistic for this sample? (Report answer accurate to three decimal places.)test statistic = What is the p-value for this sample? (Report answer accurate to four decimal places.)p-value = The p-value is... less than (or equal to) αα greater than αα Correct This test statistic leads to a decision to... reject the null accept the null fail to reject the null Correct As such, the final conclusion is that... There is sufficient evidence to warrant rejection of the claim that the population proportion is greater than 0.72. There is not sufficient evidence to warrant rejection of the claim that the population proportion is greater than 0.72. The sample data support the claim that the population proportion is greater than 0.72. There is not…
