Sarah, a botanist, wanted to know whether the mean number of days for the plants to produce fruit where she lives is different from 87 days. She planted 40 seeds and recorded the number of days for each plant to produce fruit. With all conditions for inference met, the hypothesis test was conducted at the significance level a = 0.05, and the test resulted in a pvalue of 0.0752. Which of the following is a correct conclusion? A Sarah has convincing statistical evidence to conclude that the population mean number of days for the plants to produce fruit is greater than 87 days. B Sarah has convincing statistical evidence to conclude that the population mean number of days for the plants to produce fruit is different from 87 days. Sarah does not have convincing statistical evidence to conclude that the population…
17. A student did not believe their teacher when they stated that students tend to make more mistakes on their homework when listening to music. The students gave 30 participants two tasks: one task was given while the participant performed simple math problems and gave a similar, but different set of math problems when not listening to music. The following is the mean of the difference scores for the two tasks MD=4 and an SEM=1.3 a. State the null and alternative hypothesesb. Perform a paired samples t test with the descriptive statisticsc. Is there a significant difference between the two conditions? Test using an alpha level of .05, using the direction of the test that is listed in the question. Use APA format in answering question.
30. Who will you vote for? A simple random sample of 1500 voters were surveyed and asked whether they were planning to vote for the incumbent mayor for re-election. Seven hundred ninety-eight of them replied that they were planning to vote for the mayor. The mayor claims that more than half of all voters are planning to vote for her. To test this claim, a test of the hypotheses H0: p = 0.5 versus H1: p > 0.5 is performed. a. Show that the P-value is 0.007. b. The P-value is very small, so H0 is rejected. A pollster claims that because the P-value is very small, we can be fairly certain that the population proportion p is greater than 0.5, but we cannot be certain that it is a lot greater. Is this a correct interpretation of the P-value?
7. Suppose a researcher wants to estimate the difference in proportions of firstborn between the college graduates and non-graduates to within 0.05, with 90% confidence.

Suppose that we want to estimate the true rate r of covid-positive people in a popu- lation (where they are reluctant to disclose their status). We use the two-coin-toss method, and those who toss two heads will lie about their status, reporting the opposite status. After flipping their coins, 36% of the people report that they are covid-positive. What is our estimate for the rate r of covid-positive people in this population?
