John wishes to study the mean human body temperature. John organizes a simple random sample which allows him to measure the human body temperature of 45 people at school. His calculations show that his sample has a mean human body temperature of 98.40"F and a standard deviation of 0.62"F. Prior studies indicate that human body temperatures are normally distributed with a standard deviation of 0.50*F. Use the p-value method and a 2% significance level to test the claim that the mean human body temperature of the population is equal to 98.6'F as is commonly believed. What is the wordy conclusion? There is sufficient evidence to support the claim that the mean human body temperature of the population is equal to 98.6"F as is commonly believed. There is sufficient evidence to warrant rejection of the claim that the mean human body temperature of the population is equal to 98.6'F as is commonly believed. There is not sufficient evidence to warrant rejection of the claim that the mean human body temperature of the population is equal to 98.6"F as is commonly believed. There is not sufficient evidence to support the claim that the mean human body temperature of the population is equal to 98.6"F as is commonly believed.
