George is curious. He has been told that the average body temperature of humans is 98.6 degrees Fahrenheit. However, he believes it is much lower than that. He randomly selects 60 people from those passing by him on a street and takes their temperature. The average temperature of these 60 people is 98.2 degrees Fahrenheit. The standard deviation, sigma Subscript x, is known to be 0.62 degrees Fahrenheit. The p-value is less than 0.0001. What is the correct conclusion?

Since the p value is a very low value we have enough evidence to reject the null hypothesis in favor of the alternative hypothesis and we can conclude that the true mean for this case is significantly different from 98.6 F at any usual significance level used.

Step-by-step explanation:

Information given

represent the sample mean

represent the population standard deviation

sample size  

represent the value that we want to test

t would represent the statistic

represent the p value

System of hypothesis

We want to verify if the true mean is equal to 98.6 F, the system of hypothesis would be:  

Null hypothesis:  

Alternative hypothesis:  

The statistic is given by:

 (1)  

The degrees of freedom, on this case:  

The p value would be given by:

Since the p value is a very low value we have enough evidence to reject the null hypothesis in favor of the alternative hypothesis and we can conclude that the true mean for this case is significantly different from 98.6 F at any usual significance level used.

step-by-step explanation: the answer is 27. first multiply .32 by 25 which equals 8. then add 8 to 25 which gives you 33. then you subtract that from 6 since she gave 6 to her brother.
