What is your conclusion in the context of the problem? 0 At 10% level of significance, the prevalence of self-reported obesity among Michigan residents is less than or equal to 35%. 0 At 10% level of significance, the prevalence of self-reported obesity among Michigan residents is less than or equal to 40%. 0 At 10% level of significance, the number of self-reported obese Michigan adult residents is more than 98. 0 At 10% level of significance, the prevalence of self-reported obesity among Michigan adult residents is more than 35%. 0 At 10% level of significance, the prevalence of self-reported obesity among Michigan residents is more than 40%. Question 5 (2 points) Question 4 (2 points) From the Behavioral Risk Factor Surveillance System in 2019, the prevalence of self- reported obesity among Michigan adult residents was 35.0%. Moreover, national reports from American Heart Association and Mayo Clinic state that people are more inactive than they used to because of the COVID-19 preventive measures. With this, you are hypothesizing that this year, the proportion of people categorized as obese is higher than before. To verify this, a random sample of 245 individuals were randomly selected from the different counties. Out of the sample, 98 of them were classified as obese. Using 10% level of significance, perform a test of significance.

If they do not differ in weight from 5 pounds, on average after intake, then he will buy bulk amounts of that vitamin brand. To make his decision, he randomly selected 15 chickens and weighed them after weeks of supplementing them with the vitamins. It is found that the sample has a mean weight of 5.15 pounds, with standard deviation of 0.42 pounds. Should he invest on the vitamins or not? Conduct a hypothesis test at 5% level of significance. What are the appropriate null and alternative hypotheses? OHo : M 5. 15 O Ho : M 5 OHo : M 2 5 vs Ha : M 0.1 O Reject HA since the pvalue 0.1
