What is normal, when it comes to people's body temperature? a random sample of 130 human body temperatures, provided by allen shoemaker in the journal of statistical education, had a mean of 98.25◦ and a standard deviation of 0.73◦ . (a) does the data indicate that the average body temperature for healthy humans is different from 98.6◦ , the usual average temperature cited by physicians and others? test using α = 0.01. (b) what is the p-value?

The two-sided alternative hypothesis is appropriate in this case, the reason being we are asked "does the data indicate that the average body temperature for healthy humans is different from 98.6◦........?".
The test statistic is:

Using an inverse normal table, and halving  for a two-tailed test, we look up  and find the critical value to be Z = 2.5758.
Comparing the test statistic Z = -5.47 with the rejection region Z < -2.5758 and Z > 2.5758. we find the test statistic lies in the rejection region. Therefore the evidence does not indicate that the average body temperature for healthy humans is different from 98.6◦.
 

What exactly is your question?

At a constant it will take one hour to travel 32 mi.at that speed it will take 1/2 hr to travel the remaining 16 mi.it will take 1+1/2 hr to travel the 48mi @ 32mph.so 1 hr = 60 min& 1/2 hr = 30 min1+1/2 hr = 90 min.there are 60s in each 90 × 60 = 3600 seconds.the real question seriously is he why are they driving so slow? ! lol.
