We wish to check that normal body temperature may be more than 98.6 degrees for a certain population. In a random sample of 18 individuals from this population, the sample mean was found to be 98.87 and the sample standard deviation was 0.482. Assume the population is normally distributed. Use a = 0.05 a. Normal body temperature is lower than 98.6 degrees, since p value is less than 0.05 b. Normal body temperature is lower than 98.6 degrees, since p value is negative. c. Normal body temperature is higher than 98.6 degrees, since p value is greater than 0.05.  d. Normal body temperature is higher than 98.6 degrees, since p value is less than 0.05.

Question

We wish to check that normal body temperature may be more than 98.6 degrees for a certain population. In a random sample of 18 individuals from this population, the sample mean was found to be 98.87 and the sample standard deviation was 0.482. Assume the population is normally distributed. Use a = 0.05

a. Normal body temperature is lower than 98.6 degrees, since p value is less than 0.05

b. Normal body temperature is lower than 98.6 degrees, since p value is negative.

c. Normal body temperature is higher than 98.6 degrees, since p value is greater than 0.05. 

d. Normal body temperature is higher than 98.6 degrees, since p value is less than 0.05.
