Answer:
171
Step-by-step explanation:
Q~r
find k (k is the constant)
Q=kr
76=k×20
76=20k divide 20 on both sides giving you
k=3.8
then Q=k×r
Q=3.8×45
Q=171
Answer: 1.460
Step-by-step explanation:
Given : Researchers report that on average freshman who live on campus gain 15 pounds during their first year in college.
Let
represents the population mean .
Then, the set of hypothesis will be:-


We assume that this is normal distribution.
Sample size : n = 10, which is a small sample (n<30) ,s o we use t-test.
Sample mean : 
Standard deviation : 
The test statistic for population mean for small sample is given by :-


Hence , the value of test statistic = 1.460
Answer:
box plot with minimum value 2.3, lower quartile 2.4, median 2.6, upper quartile 2.7, and maximum value 2.8
that is the right answer because we have 2.3 one time that is minum then 2.4 two times that means lower 2.5 2 times but this is not middle because total 11 times calculation are given and middle is of 2.6 upper of 2.7 two times and maximum 2.8 two times
Is this a multiple choice answer? If not, the answer is E. Ash from human cremations
