Answer:
a) the value of 135 because it is not greater than 136.5
Step-by-step explanation:
Given that
n = sample size =85
Mean = 146
std dev =34
Std error of sample = 34/sqrt 85
= 3.6878
99% z critical value = 2.58
Margin of error = ±9.515
Confidence interval lower bound = 146-9.515 = 136.485
Upper bound = 146+9.515 =155.515
Hence we find that 135 is less than lower bound, hence 135 does not lie within 99% confidence interval
a) the value of 135 because it is not greater than 136.5
The answer is A.
The example sort of doesn't make sense but in essence what you would do is divide the 366mins by 60 min (366/60) in order to know how many hours are in 366min.
Answer:
Correct option is B.
Step-by-step explanation:
Given the radius of circle and the angle in sector we have to find the area of shaded region i.e minor sector.





∴ Area of sector is
