Answer: a) 1082, b) wider.
Step-by-step explanation:
Since we have given that
Margin of error = 0.1 millimeter = E
Standard deviation = 2 mm = σ
Critical value would be
a) Sample size would be
b) Sample size, n = 100
So, the margin of error would be
Since the margin of error in b part is more than a part, as we know that the higher the margin of error, the wider the confidence interval.
So, it would have wider confidence interval.
Hence, a) 1082, b) wider.
The length of the leg a of the right triangle is obtained by applying the Pythagorean theorem which is given as:
Thus, we have that:
Given that b = 21.5 inches and c = 31.9 inches, we now have:
Therefore, the length of the leg a of the right triangle is 23.6 inches
