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?

Researchers from a certain country were interested in how characteristics of the spleen of residents in their tropical environment compare to those found elsewhere in the world. The researchers randomly sampled 91 males and 109 females in their country. The mean and standard deviation of the spleen lengths for the males were 10.9 cm and 0.9 cm, respectively, and those for the females were 9.8 cm and 1.1 cm, respectively. Determine a 95% confidence interval for the difference between mean spleen lengths of males and females in this country. Click here to view page 1 of the table of critical values of t.
