C. m < 1 = 90, m < 2 = 14, and m < 3 = 76 is the measure of the numbered angles in the rhombus. The diagram is not drawn to scale.
I believe the answer is C
Answer:
The standard error of the mean = 5.14 mins
Step-by-step explanation:
Number of random sample (n) = 20
Mean(X) = 31.25 mins
Standard deviation (α) = 23.7 mins
Standard error of mean =
standard deviation / √sample size
= 23.7/√20
= 23.7/4.4721
= 5.14 mins
