Answer:
2) ![\frac{1}{4} c](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4%7D%20c)
3/4 of the cyclists did not finish, thus 1/4 did.
3) ![59-t](https://tex.z-dn.net/?f=59-t)
56 people were on the bus. 3 people got on(56+3=59). Then t people got off(-t)
4) ![\frac{G}{30}](https://tex.z-dn.net/?f=%5Cfrac%7BG%7D%7B30%7D)
Out of 30 people, g of the are girls
5) ![\frac{16}{c}](https://tex.z-dn.net/?f=%5Cfrac%7B16%7D%7Bc%7D)
Out of c people, 16 are boys
Hope it helps <3
Answer:
The mean of 7 and 38 is 22.5.
Step-by-step explanation:
Mean: Mean the average of the numbers or in other words it is the sum of numbers divided by the count.
Here the numbers are 7 and 38 and the count is 2
therefore,
![\textrm{Mean of 7 and 38} = \frac{Sum}{Count} \\= \frac{7+38}{2} \\= \frac{45}{2}\\ = 22.5](https://tex.z-dn.net/?f=%5Ctextrm%7BMean%20of%207%20and%2038%7D%20%3D%20%5Cfrac%7BSum%7D%7BCount%7D%20%5C%5C%3D%20%5Cfrac%7B7%2B38%7D%7B2%7D%20%5C%5C%3D%20%5Cfrac%7B45%7D%7B2%7D%5C%5C%20%3D%2022.5)
Answer:
Yes
Step-by-step explanation:
Given that :
CHAIN A:
Sample size n1 = 30
Sample standard deviation of waiting time s1 = 21.2
CHAIN B:
Sample size, n2 = 28
Sample standard deviation of waiting time s2 = 31.4
Null hypothesis H0: s1 = s2
Alternative hypothesis H1: s1 < s2
Test statistic ; Ftest : s1² / s2²
Ftest = 21.2^2 / 31.4^2
= 0.4558399
P value from F statistic : = 0.02 (using p value calculator)
Since the pval < 0.05
Then we reject the Null ; Chain A waiting time is more consistent
