Test Prep. A GRE prep company claims that average score improvement of their students is equal to 50points. We randomly sample 40 students of their average improvement is 47 points with a standarddeviation of 37 points. Evaluate the company's claim using a hypothesis test. Use a 5% level of significance.(a) Write the hypotheses for the test:OHo: H = 50Hạ: p < 50O H.: H = 47Hạ: p< 47O H:: µ = 50Hạ: p = 50OH,: µ = 47Hạ: p > 47%3DO H,: µ = 50Ha: p > 50%3DOHo: H = 47Ha: p = 47(b) Compute the p-value for the test:p =|(round to three sig figs)(c) What is the final conclusion?O There is not sufficient evidence to reject the company's claim.O There is sufficient evidence to support the company's claim.O There is not sufficient evidence to support the company's claim.O There is sufficient evidence to reject the company's claim.Question Help: M Message instructor D Post to forumSubmit All PartsJump to Answer

The following hypotheses are given to determine an One-Tail testing. H0: p≤0 Ha: p >0 A random sample of 10 paired observations indicated a correlation (r) of .35. Can we conclude that the correlation in the population is greater than zero by performing the t-statistic? By using the .05 significance level, what is the p-value or critial value?____________ What is your decision regarding Ho or the null hypothosis? The Airline Passenger Association studied the relationship between the number of passengers on a particular flight and the cost of the flight. It seems logical that more passengers on the flight will result in more weight and more luaggage, which in turn will result in higher fuel costs. For a sample of 13 flights, the correlation between the number of passengers and total fuel cost was .37. Is it reasonable to conclude that there is positive association in the population between the two variables? H0: p≤0 Ha: p >0 Use the 5%…
A hypothesis was done using Ho: p=15% HA: p>15% The hypothesis test where p= the percentage of Americans who regularly listen to music that have hearing loss. The hypothesis test used alpha= .01 and the p-value of the test was .0007. The correct conclusion for this test is
A century ago, the average height of adult women in the United States was 63 inches. Researchers believe that the average might be greater today. A random sample of 40 adult women was selected from the population. The sample had mean 64.2 inches and standard deviation 2.9 inches. Assuming all conditions for inference are met, the researchers will perform an appropriate hypothesis test to investigate their belief. Which of the following is the correct test statistic for the hypothesis test? A t = 63-64.2 2.9 63-64.2 2.9 t 3= 63-64.2 29 40 64.2-63 t 3= 2.9 64.2-63 t = 2.9 US 1 DELL 么 & %24 %23 || E.

Conduct a full hypothesis testing on the following problem and then choose among the options what best fits the items being asked: Average heart rate for Filipinos is 91 beats/minute with a population standard deviation of 8.7 beats/minute. A group of 24 individuals participated in an aerobics fitness program to lower their heart rate. After six months the group was evaluated to identify if the program had significantly slowed their heart. The mean heart rate for the group was 88 beats/minute. Was the aerobics program effective in lowering heart rate at 5% significance level? Note: Round off the test statistic to 3 decimal places. If two-tailed test is to be applied, the given critical values as options are considered the absolute values. Identify the following: - Alternative Hypothesis: [Select] • Critical Value: [Select] - Test Statistic: [ Select] • Conclusion: [ Select]

The 2nd population's sample has 47 successes and a sample size = 396. 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... O less than (or equal to) a greater than a This test statistic leads to a decision to... reject the null O fail to reject the null accept the null As such, the final conclusion is that... O The sample data support the alternate hypothesis claim that p1 > p2. O There is not sufficient sample evidence to support the alternate hypothesis claim that p1 > p2.
