8. Take a sample of 30 females from your data a. Show your sample b. Find the proportion of female cat owners out of these females 9. Take a sample of 30 males from your data a. Show your sample b. Find the proportion of male cat owners out of these males 10. Using the results of #8 and #9, test the claim that females have a higher proportion of cat ownership than males. a. State the null and alternative b. State the test statistic c. Use the p-value to make a decision (reject or fail to reject) d. Graph the test statistic, p-value, and a=0.05 e. Write your conclusion in terms of the problem Out of 117 People, only 42 People own cuts.

It is 50% chance of owning the cat. Based on the population that I got in question 2 it doesn't look like they are equal. Dwn 7) To test Ho : P = 56% against H.P750s at br level of significance.

From the sample of 50 you took from the previous benchmark (or you can just take a new sample of 50) record whether they owned a cat or not. You can use the table below, make another one, or use excel: 2. Find the proportion of people who own cats from this sample. 3. Create a 95% confidence interval for the true population proportion of cat owners based on your sample. In words write what the confidence interval means in terms of our data. 4. Find the margin of error for your confidence interval 5. If I believe that people are just as likely to own a cat than to not own a cat a. What do I believe the proportion or percentage of cat owners is? (For example is it 0.20 or 20% are cat owners? Or some other percentage?) b. Looking at the proportion from part (a), do you believe it is possible that the true proportion of cat owners is what I am claiming? Why or why not? (is it in the interval you made?) 6. Again I claim that people are just as likely to either own a cat or not own a cat. Based on the proportion you found in #2 do you believe I am correct? Or do you think the true proportion is more? Is it less? 7. Test my claim that people are just as likely to either own a cat or not versus what you stated in #6. Or if you believed that I am correct test my claim against the proportion just being different (not equal to my claim) than my claim. Use a significance level of a = 0.05. a. State the null and alternative b. State the test statistic Use the p-value to make a decision (reject or fail to reject) d. Graph the test statistic, p-value, and a e.
