Use the given information to calculate and interpret the test
statistic and effect size.
Hypotheses: H0: μ=20 vs. HA: μ≠20
Sample data
The test statistic is?
=This means that the point estimate is_____ standard errors below the null value.
The effect size is ______ , which can be considered (select answer: Small, moderate, large) Differences between the point estimate and the null value will not be noticeable without careful observation.
Test Statistic = ( - μ) / SE
= (19.8 - 20) / 0.25
= -0.8
This means that the point estimate is 0.8 standard errors below the null value
Effect size = | - μ| / SD
= |19.8 - 20| / 1.5
= 0.1333
Since the effect size is less than 0.20, the effect size is Small

A hypothesis test is used to test the hypotheses H0: μ = 10.5 versus HA: μ > 10.5 where μ = the mean weight of a one-year old tabby cat. Based on a random sample of 21 cats, a p-value of 0.0234 is found. a) Using α = 0.05, what is the conclusion for this test, reject or fail to reject the null hypothesis? b) Based on your answer to part b, what type of error did you possibly make,...
Consider the following hypotheses: H0: μ = 9,100 HA: μ ≠ 9,100 The population is normally distributed with a population standard deviation of 700. Compute the value of the test statistic and the resulting p-value for each of the following sample results. For each sample, determine if you can "reject/do not reject" the null hypothesis at the 10% significance level. (You may find it useful to reference the appropriate table: z table or t table) (Negative values should be indicated...
