Suppose that the size of a type of bacteria is normally distributed with a mean of μ0={m} micrometers and a standard deviation of {s} micrometers, in 2010. A research believed that the bacteria has grown over the last decade. To find out if his/her belief is true, the researcher collected a SRS of 25 bacteria and would like to test if the mean bacteria size now is greater than the record in 2010. The sample mean is {b}. Perform a formal hypothesis test that includes all steps on your worksheet, includin : 1) hypothesis;   (2)   calculation of test statistic;  and (3) p-value Enter the test-statistic here (Keep 2 decimals):

A surgical resident has a success rate of {p} for brain tumor surgery. The resident is supposed to complete {n} operations in a row. Assume that the probability of success does not change. The probability of fewer than 2 successes is: Round the raw values to the 4th decimal place. Do not use % scale. Show your work on the worksheet

A sample of 6 subjects were randomly selected from a community to examine their average cholesterol level: {x1}, {x2}, {x3},{x4}, {x5}, {x6}. Calculate the sample standard deviation. Show your work on the worksheet. (Round to the 1st decimal place).

Suppose that the systolic blood pressure levels varied according to a normal distribution with a mean score of 150 mmHg and a standard deviation of 10 among hypertension patients that are not on medication The probability of the blood pressure higher than 160 mmHg in this population is___. (Round to the 4th decimal place, do not use % scale) The probability of the blood pressure between 150 and 160 mmHg in this population is___. (Round to the 4th decimal place, do not use % scale)  The blood pressure level corresponding to the top 5th percentile is___mmHg . (Round to the 1st decimal place)

The researcher wants to test if the mean bacteria size f μ0 now is different from the mean size in 2010. Find the correct hypotheses.

Scan and upload your work sheet(s) in one document for the calculation questions: Show your steps including the equations and plugged-in numbers

Based on the p-value in the previous question, we can conclude that the 95% confidence interval for the sample mean
