The computed P-Value = 0.011 Should H0 be rejected?: Fail to Reject H_0 Reject H_0 What is the correct conclusion? There IS sufficient evidence to reject the Null Hypothesis and accept the alternative. There is NOT sufficient evidence to reject the Null Hypothesis and accept the alternative.

The following display from a TI-84 Plus calculator presents the results of a hypothesis test. Z-Test u#37 z = 1.947543 p=0.051470 x = 38.80 n = 45 What is the value of the test statistic? O 0.051470 1.947543 O 38.80 O 37 No new data to save. Last checked at 8:00pm Submit Qu

20% of all college students volunteer their time. Is the percentage of college students who are volunteers smaller for students receiving financial aid? Of the 326 randomly selected students who receive financial aid, 46 of them volunteered their time. What can be concluded at the αα = 0.05 level of significance? Z- test for a population proportion The null and alternative hypotheses would be:       H0:H0: p =  __?__  (please enter a decimal)           H1:H1:  p is ( choose one   <, = or not equal)           ____?___ncorr  __?__(Please enter a decimal)     The test statistic z=    __?__(please show your answer to 3 decimal places.)   The p-value =  __?__(Please show your answer to 4 decimal places.)     Thus, the final conclusion is that ... a. The data suggest the population proportion is not significantly lower than 20% at αα = 0.05, so there is insufficient evidence to conclude that the percentage of financial aid recipients who volunteer is lower than 20%. b. The data…

If, in a sample of n = 25 selected from a normal population, X = 57 and S= 10, what is the value of tSTAT if you are testing the null hypothesis Ho: μ = 50? tSTAT = (Type an integer or a decimal.)

If, in a sample of n = 16 selected from a normal population, X= 51 and S = 8, what is the value of tSTAT if you are testing the null hypothesis Ho: µ= 50? tSTAT = (Type an integer or a decimal.)

Find the P-value for a left-tailed hypothesis test with a test statistic of z = - 1.68. Decide whether to reject H, if the level of significance is a= 0.10. P-value = (Round to four decimal places as needed.) State your conclusion. Choose the correct answer below. O Since P>a, fail to reject Ho- O Since P>a, reject Ho- O Since Psa, fail to reject Ho- OS ince Psa, reject Ho-

The one-sample t-statistic for a test of Ho: u = 42 versus H1:µ < 42 based on n = 15 observations has the value t = -2.138, where Ho and Hjare the null and alternative hypotheses, respectively. The sample size is denoted by n. Use this t-table to determine which two P-values bracket the P-value of the test. Report your answers in decimal form as listed in the t-table. P-value of the test <

A police office claims that the proportion of people wearing seat belts is less than 65%. To test this claim, a random sample of 200 drivers is taken and its determined that 126 people are wearing seat belts. The following is the setup for this hypothesis test: Ho :p-0.65 Ha : p < 0.65 In this example, the p-value was determined to be 0.277 come to a conclusion and interpret the results for this hypothesis test for a proportion (use a significance level of 5%) Select the correct answer below: O The decision is to reject the Null Hypothesis. The conclusion is that there is enough evidence to support the claim The decision is to fail to reject the Null Hypothesis. The conclusion is that there is not enough evidence to support the claim

It is dec to investigate whether there is a relationship between the attendance status at a faculty and the passing grade. The attendance status and passing grades of a sample of 100 students taken from the faculty were examined and the following table was obtained. Which of the following is incorrect for the relevant hypothesis test? (take α=0.01.)passing grade <50    50-<70     70-<=100continued       14         20             11sometimes      12          17            8very few           3           5              10  A)The calculated test statistic is χ2=7,625. B)The passing grade is associated with the attendance status. C)The table value is χ2=13.28. D)the contribution of cell "e33" to the chi-square value is 4.38.

A random sample of 144 recent donations at a certain blood bank reveals that 86 were type A blood. Does this suggest that the actual percentage of type A donations differs from 40%, the percentage of the population having type A blood? Carry out a test of the appropriate hypotheses using a significance level of 0.01. In USE SALT State the appropriate null and alternative hypotheses. O H: p = 0.40 H:p 0.40 O Ho: p + 0.40 H: p = 0.40 O H: p = 0.40 H:p + 0.40 Calculate the test statistic and determine the P-value. (Round your test statistic to two decimal places and your P-value to four decimal places.) Z = P-value = State the conclusion in the problem context. O Reject the null hypothesis. There is sufficient evidence to conclude that the percentage of type A donations differs from 40%. O Do not reject the null hypothesis. There is sufficient evidence to conclude that the percentage of type A donations differs from 40%. O Do not reject the null hypothesis. There is not sufficient…
