A pumpkin farmer weighed a simple random sample of sizen= 20 pumpkins, with these results:9.6, 8.8, 5.1, 9.7, 9.1, 8.9, 8, 9.2, 2.7, 9.1, 8.5, 7.3, 9.3, 9.6, 4.1, 9.9, 7.6, 9, 7.2, 8.5
1.how to use R to perform the bootstrap with 2000 resamplings to create a90% confidence interval forμ
2.how to know whether the true mean pumpkin weight for this pumpkin farmer’s patchis greater than 7.2. Conduct a bootstrap hypothesis test with 2000 resamplings at a significance levelα= 0.05.
3.how to conduct a hypothesis test at levelα= 0.05 to see whether we can assert the data are strong evidencethe true median weight for this pumpkin farmer’s patch is greater than 7.2.
Solutions
Expert Solution
1)
The lower limit of the 95% confidence interval for the true mean is 7.27975 and greater than 7.2. Hence, we can conclude that the true mean pumpkin weight for this pumpkin farmer’s patches greater than 7.2 at a significance levelα= 0.05.
# 3
The P-value is 0.1606 and greater than 0.05 level of significance. Hence, the data are not strong evidence the true median weight for this pumpkin farmer’s patch is greater than 7.2.

A simple random sample of pulse rates of 20 women from a
normally distributed population results in a standard deviation of
12.2beats per minute. The normal range of pulse rates of adults is
typically given as 60 to 100 beats per minute. If the range rule of
thumb is applied to that normal range, the result is a standard
deviation of 10 beats per minute. Use the sample results with a
0.01 significance level to test the claim that pulse...
