A random sample of 10 independent healthy people showed the body temperatures given below (in degrees Fahrenheit). Test the hypothesis that the population mean is not 98.6 °F, using a significance level of 0.05. 98.3 98.5 99.0 96.2 98.4 98.9 97.8 99.3 98.7 97.4 O Ha: u# 98.6 Hg:= 98.6 Hu< 98.6 Check the conditions to see whether the test statistic will follow a t-distribution. The sample V random and the observations V independent. The distribution of the sample is Find the test statistic. (Round to two decimal places as needed.) Find the p-value. p-value =D (Round to three decimal places as needed.) Interpret the results of the test. Since the p-value is the significance level, Ho. There is V evidence to conclude that the population mean is not 98.6°F at a significance level of 0.05.
