- Which of the following does not need to be satisfied in order to conduct this hypothesis test using theoretical methods?
- Point price of one 0.99 carat diamond in the sample should be independent of another, and the point price of one 1 carat diamond should independent of another as well
- Point prices of 0.99 carat and 1 carat diamonds in the sample should be independent.
- Distributions of point prices of 0.99 and 1 carat diamonds should not be extremely skewed
- Both sample sizes should be at least 30

In order to conduct a hypothesis test for the population mean, a random sample of 14 observations is drawn from a normally distributed population. The resulting sample mean and sample standard deviation are calculated as 77 and 2.0, respectively.

(Round all intermediate calculations to at least 4 decimal places.) In order to conduct a hypothesis test for the population variance, you compute s2 = 68 from a sample of 12 observations drawn from a normally distributed population. Use the critical value approach to conduct the following tests at α = 0.05. Use Table 3. H0: σ2 ≤ 37; HA: σ2 > 37 a-1. Calculate the value of the test statistic.

Part 1: Hypothesis Testing (25 points) Step 1: Suppose you are asked to conduct a hypothesis test on the population mean. What type of hypothesis test would you use? What assumptions do you need to make about the process when you are conducting a hypothesis test on the population mean in order for your results to be valid? This needs to be at least one (1) paragraph in length. Note a paragraph contains at least three complete sentences. Watch your...

Suppose you were hired to conduct a study to find out which of two brands of soda college students think taste better. In your study, students are given a blind taste test. Your students rated one brand first, and then they rated the other, in random order. The ratings are given on a scale of 1 (awful) to 5 (delicious). Which type of hypothesis test would be the best to compare these ratings? O 2-dependent sample t-test O 2 independent...

Conduct an independent samples t-test (a.k.a., between-subjects design). Each sample should have at least n=8 individuals. What to turn in: 1. What is your research question? 2. State the null (Ho) and alternative (H1) hypotheses. 3. Conduct the hypothesis test using an alpha level of .05, and state your conclusion (Reject Ho/Fail to Reject Ho) regarding the original hypotheses. 4. Calculate and interpret a measure of effect size (est. Cohen's d or r2) and a 95% confidence interval.
