Explanation:
I'm not entirely sure, it could be B, or D. my research has made me lean more to B though..
Claim: the mean resting pulse rate for men is less than 72
bpm.
Symbolic form would be: μ < 72
Step 1: null hypothesis : μ > = 7 2 b p m
Step 2: alternative hypothesis: μ < 7 2 b p m
Step 3: the test statistic is z = mean – μ / standard dev/sqrt (n) = -3/4 / 1.7639 = -1.92
Step 4: c v method: since z α = -1.645, the test static is z = -1.92 is less than the CV, we reject null hypothesis
P Value method: area is 0.0274, since the p value is <= α, reject null hypothesis.
Step 5: the sample data support the claim that the mean resting pulse rate for men is less than 72 bpm.

Explanation:
Volume = length * breadth * height
here length= breadth= height
isometrically (increasing all our dimensions at the same rate during growth)
L_1= 1.8 m = 180 cm
L_2= 50 cm
keeping all other dimensions same we can write
So volume ratio = (L1/L2)^3
= (180/50)^3
= 46.65
