A sample is selected from a population with μ= 50. After a treatment is administered to the individuals in the sample, the mean is found to be M= 55 and the variance is s2= 64. a. For a sample of n = 4 scores, conduct a hypothesis test to evaluate the significance of the treatment effect and calculate Cohen’s d to measure the size of the treatment effect. Use a two-tailed test with α = .05. b. For a sample of n = 16 scores, conduct a hypothesis test to evaluate the significance of the treatment effect and calculate Cohen’s d to measure the size of the treatment effect. Use a two-tailed test with α = .05.1.State hypotheses 2.Locate critical region using the t-table, df, and alpha3.Calculate t-statistic 4.Make a decision regarding Ho (null hypothesis) c. Describe how increasing the size of the sample affects the likelihood of rejecting the null hypothesis and the measure of effect size.
State the H0 (null Hypothesis) and H1 (Claim, Alternative Hypothesis). Identify the claim. Determine whether the test is either left, right or two tailed tests. Show in the sketch of graph. Find the critical value Zα and label on the graph. This is the reject H0 Calculate the test statistic. Make our decision about H0. Interpret the decision. It is claimed that the mean weight of the shipping containers at the port is 1030 kg. α = 0.01, = 1033, s = 5.7 and n=17 Note: σ for population is unknown
The one-sample t-statistic for a test of Ho: µ = 42 versus H1: µ < 42 based on n = 15 observations has the value t = -0.867, where Họ 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. k P-value of the test <
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 <
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?
A sample of 30 observations is selected from a normal population. The sample mean is 59, and the population standard deviation is 8. Conduct the following test of hypothesis using the 0.02 significance level.H0: μ = 62H1: μ ≠ 62 a. Is this a one- or two-tailed test? (One-tailed or Two-tailed) b. What is the decision rule? (Reject H0 if −2.326 < z < 2.326 or Reject H0 if z < −2.326 or z > 2.326) c. What is the value of the test statistic? (Negative amount should be indicated by a minus sign. Round your answer to 2 decimal places.)The value of the test statistic is d. What is your decision regarding H0? (Reject H0 or Fail to reject H0) e-1. What is the p-value? (Round your z value to 2 decimal places and final answer to 4 decimal places.)The p-value is e-2. Interpret the p-value? (Round your z value to 2 decimal places and final answer to 2 decimal places.)There is a % chance of finding a z value this large by "sampling error" When H0 is true.
