Given the following null and alternative hypotheses, conduct a hypothesis test using an alpha equal to 0.05. (Note: The population standard deviations are assumed to be known.) H0: µ1 ≤ µ2 HA: µ1 > µ2 The sample means for the two populations are shown as follows: sample mean 1 = 144, sample mean 2 = 129 population standard deviation 1 = 11, population standard deviation 2 = 16 sample size 1 = 40, sample size 2 = 50 Answer: Decision Rule : Reject H0 if Zcal > citical value Z = Test statistic: (Z calculated) Zcal = (use 4 decimal places)Conclusion: H0.
Laura asks whether the type of school students attend (private versus public) results in different performance on a test. A sample of N=100 students from a private school produce a mean of 71.30 on a test, and the mean of the population of public school students is µ=75.62 with ?௫ =28. a. Write the alternative hypothesis. b. Write the null hypothesis. c. With α=.05, what is zcrit? d. Compute zobt e. What should Laura conclude?
The NAEP considers that a national average of 283 is an acceptable performance. Using α = .05, run a two-tail t-test for one sample to test Ho: µ=283 for the 2019 scores. Report the t-obt, df, and p-values. Would you reject the null hypothesis that the 2019 scores come from a population with average 283? If this is the case, does it come from a population from larger or smaller average?
Q1. Which of the following represents Type II error? a. Rejecting the Ho after a test statistic results in a p-value of 0.10 at α =0.05.B. Rejecting the Ho after a test statistic results in a p-value of 0.025 at α=0.05.C. None of the above
12. Two independent samples are taken from two populations. Sample 1 has a mean of 12.8, a standard deviation of 2.3, and a sample size of 18. Sample 2 has a mean of 14.2, a standard deviation of 5.2, and a sample size of 23. This gives a standard error se(Ã1 — Ă2) = 1.212. A 95% confidence interval for the difference between the two means is: (A) (-2.00, -0.80). (B) (11.66, 13.94). (C) (-3.96, 1.16). (D) (-3.85, 1.05). (E) (-3.78, 0.98).
