July 9, 2019I need some guidance for the following question:
A researcher wishes to estimate the meanage of all runners who participate in the annual Vancouver marathon. A random sampleof 36 participants indicated a mean age of 31.4 years. It is known that the population standard deviationof ages is sigma=7.2 years.
Construct a 97% confidence intervalfor the population mean age.
Note: express the confidence interval to 2 decimal places of accuracy.
This solution goes over how to construct a 97% confidence interval for annual Vancouver marathon runners.
