Answer:
mean: 32.3
proportion: 0.025
Step-by-step explanation:
Mean = sum/n
Mean = 1292/40
= 32.3
Number of data values less than 26:
1
Proportion: 1/40 = 0.025
We are given the following data
n = 35
x = 50
s = 2
CI = 95% (z = 1.96)
The formula for the margin of error is
E = z s / √n
Substituting the given values
E = 1.96 (2) / √35)
E = 0.66 or 66%
