The answer should be B. Hope this helped
First we find the circumference
c=2pir
r=3
2pi3
6pi=c
then find out how much of the circle is 50 degreese
50/360=5/36
6pi times 5/36=5pi/6=aprox 2.62
it should be 5pi/6
Answer:
832,460, or any other number between 832,458 and 832,500
Answer:
Standard error = 0.34
t-statistic = 11.18
Step-by-step explanation:
Given Data:
Mean difference d = 3.8
Standard deviation S.D = 1.36
Number of people = 16
The appropriate test are:
1. Standard error
2. T- statistic
1. Calculating the standard error using the formula;
Standard error = S.D/√n
= 1.36/√16
= 1.36/4
= 0.34
2. Calculating the t-statistic using the formula;
t-statistic = d/(S.D/√n)
= 3.8/(1.36/√16)
= 3.8/(1.36/4)
= 3.8/0.34
= 11.18
True cause 3 is and odd number
