Suppose that you want to test the null hypothesis that one-third of all adults in your county have a tattoo, against a two-sided alternative. In other words, you'd like to assess the hypotheses:

(Ho: p = 0.33333) (Ha: p does not equal 0.33333)

For each of the following parts, create your own example of a sample of 100 people that satisfies the indicated property. Do this by providing the sample numbers with a tattoo and without a tattoo. Also report the test statistic and p-value from a one-proportion z-test.

a) Provide the sample numbers with and without a tattoo such that the two-sided p-value is less than 0.001. Report your test statistic and p-value.

b) The same as above, but so that the two-sided p-value is greater than 0.20.

You will perform a Two Sample Hypothesis Test for Proportions. For the Hypothesis Test, make sure to report the following steps: Identify the null hypothesis, Ho, and the alternative hypothesis, Ha. Determine whether the hypothesis test is left-tailed, right-tailed, or two-tailed. Find the critical value(s) and identify the rejection region(s). Find the appropriate standardized test statistic. If convenient, use technology. Decide whether to reject or fail to reject the null hypothesis. Interpret the decision in the context of the original...

Bothale and Mmabatho are collaborating to test the hypothesis that the mean reading time of adults with ASD is less than 100. Consider the following information and assume a 5% level of significance. Mmabatho the Social Scientist took a random sample of 30 adults with Autism Spectrum Disorder (ASD) and found their reading time to be normally distributed with sample mean and sample standard deviation of 90 wpm and 19 wpm respectively. Which of the following statement is incorrect? (1)...

Assume that the population variance is unknown. We test the hypothesis that Ho: µ=5 against the one-sided alternative H1: µ≠5 at a level of significance of 5% and with a sample size of n=30. We calculate a test statistic = -1.699. The p-value of this hypothesis test is approximately ? %. Write your answer in percent form. In other words, write 5% as 5.0.
