Calculate corresponding t value or s value

1)    Construct a 99% confidence interval for the population mean µ.  

2)    At what significance level do the data provide good evidence that the average body temperature is NOT 98.6  

3)    If the sample size, the sample mean, and population mean were the same as those calculated in part 2) but we calculate a t value that is significant only at the level of P = 0.10 or 10%, what could we conclude about the standard deviation s of the sample? (So n and  and u are the same as found in 2). Given that the t value is significant at .10 or 10%, what must the corresponding s value be?
