Question 939174
Ho: u =16.1 (claim)
Ha: u  < 16.1
Sample: n = 70, mean = 15.94
s = .9
...
test stat {{{z =blue (x - mu)/blue(sigma/sqrt(n))}}} : 
P(z <{{{ - .16/(.9/sqrt(70)))}}}) = (-100, -1.49) = .0681
....
significance level of 0.10.
.0681 < .10
reject Ho
A.
 The z of - 1.49 provides sufficient evidence to conclude that the mean amount of juice is less than 16.1 oz.
