Exam 2 Math 200 Fall 2019-03 7. A random sample of 31 people in a nursing home had a mean systolic blood pressure of 153 mmHg and standard deviation of 35 mmHg. Find the 90% confidence interval for the mean blood pressure of people in the nursing home. Interpret the result. Name:
An auditor takes a random sample of 880880 invoices from the 9510 invoices relating to the activities of a company in 2019. The sample mean value of the sampled invoices was £126 and the sample standard deviation was £58. Find a 99% confidence interval for the mean value of all the invoices for 2019. Round to 3 decimal places The records of the company states that the total income from the 9510 invoices was £1150710. The auditor's sample evidence does not support this stated total. True or false? What is the probability, rounded to 3 decimal places, that the company's income does not exceed the value in the records?
