... The “p adj” provide p-values for simultaneous tests of the null hypotheses H0: µ1 = µ2, etc. Here, note that the only one that cannot be rejected is the one comparing Middle to Back. So population mean GPAs for those two groups do not differ significantly. ...

... #11 a) the less sure we need to be the narrower we can make the interval, so 90% is less sure so I could build a narrower interval, it would be 98.28 +-1.676*.094 = (98.1, 98.4) b) the more sure interval makes it more likely that we have the true (all people’s) mean body temperature identified but ...
