Independent random samples of sizes n1 = 204 and n2 = 204 were taken from two populations. In the first sample, 179 of the individuals met a certain criteria whereas in the second sample, 181 of the individuals met the same criteria. Test the null hypothesis H0:p1=p2H0:p1=p2versus the alternative hypothesis HA:p1>p2HA:p1>p2. Calculate the z test statistic, testing the null hypothesis that the population proportions are equal. Round your response to at least 2 decimal places. What is the approximate value of the p-value? round to four decimal places.
A random sample of 90 observations is selected from a binomial population with unknown probability of success p. The computed value of p is 0.79. (1) Test Ho : p = 0.5 against Ha : p > 0.5. Use a = 0.01. test statistic z = critical z score The final conclusion is A. There is not sufficient evidence to reject the null hypothesis that p = 0.5. B. We can reject the null hypothesis that p = 0.5 and accept that p > 0.5.
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…
Good Morning, Based on the scenario and the data output, I would like to confirm that we would reject the null hypothesis and if so does that indicate non-signifigant or significant when relating to a CHI-Square statistical test? Thank you Scenario: In the recent COVID-19 pandemic, a local precinct observed that of the 75 people who voted, 25 identified as republican, 30 were democrat, and 20 were “other”. Is this similar to pre-pandemic voting based on political party affiliations? At that same precinct, pre-pandemic voting based on political party affiliation was: 35% republican, 44% democrats, and 21% “other”. Enter in the 75 data points and expected values into SPSS to conduct the appropriate statistical test.

An unfair die is with Pr[3] = 20% rolled 100 times. What is the expected number of times the die comes up 3? What is the variance of the number of times the die comes up 3? Let Z be a standard normal random variable. Determine Pr[2.15 >= Z >= 0.56] Determine Pr[-1.50 <= Z] Determine Pr[Z <= -1.01 or Z >= 2.02] An unfair die is with Pr[3] = 10% rolled 100 times. Using the binomial approximation, estimate Pr[8 <= K <= 13] Using the binomial approximation, estimate Pr[K = 10]
