I think it’s the last one I’m sorry if it’s wrong I’m doing the same thing in math and I just started it today
Each co-worker can get 3 whole boxes, there is one half left over
First let us calculate for the z score using the formula:
z = (x – u) / s
where x = 8, u is the mean = 12.7 years, s is the
standard deviation
z = (8 – 12.7) / 2.5
z = -1.88
From the standard probability tables, the p value at z =
-1.88 is:
P = 0.0301 = 3.01%
The left side -0.77777777 does not equal to the right side -10.8, which means that the given statement is false so it is false
Best of luck
hope i helped :)
