The mean oral temperature is not significantly less than 986.

Explanation / Answer

Question 27

The 95% confidence interval of a parameter represents that if you perform the experiment with sample sample size several times then 95% of these intervals would have the population mean.

As the 95% confidence interval (97.7, 97.8) doesn't contain the value 98.6, so we conclude that there is 0.95 probability that the mean lies between 97.7 and 97.8 Fahrenheits. Also, we can say that we are 95% confident that the mean oral temperature is significantly different from 98.6 degrees fahrenheit.

So, option (A) and (D) are correct.
