A random sample of 8 dry peaches has the following masses in g:
12.1
11.9
12.4
12.3
11.9
12.1
12.4
12.1
avg =12.5
S=0.2
1) We want to reject the peaches with mass in the lowest 10%. Calculate the lowest mass acceptable.
2) Does the sample indicate (at the 1% significance level) that the mean peach mass is 12.35 or greater?
