Answer:
Diego
Step-by-step explanation:
divide 132 minutes by 44 pages and you get 3 pages per minute, then divide 140 minutes by 35 pages and you will get 4 pages per minute. so Diego reads 1 more page a minute than lin. hope i helped you :)
Based on the characteristics of the distribution, the probability that the first goal is scored in less than 4 minutes is 0.
<h3>What is the probability?</h3>
For us to be able to calculate the probability that the first goal is scored in less than 4 minutes, the distribution needs to satisfy the requirements of the Central Limit Theorem(CLT).
Based on the fact that the distribution here is extremely right skewed, then it does not satisfy the requirements of CLT so the probability is 0.
First part of question:
The distribution of the time it takes for the first goal to be scored in a hockey game is known to be extremely right skewed with population mean 12 minutes and population standard deviation 8 minutes.

Answer:
-3
Step-by-step explanation:
Step-by-step explanation:
d=-1-5=-7+1=-6
BY using this equation:
a(n) = a1 +(n-1)d
and get the second term
a(2) = 17 +(2-1)-6
=11

Answer: No, the average age is not higher than originally believed.
Step-by-step explanation:
Since we have given that
Sample size = 20
Mean = 63.7 years
Standard deviation = 1.9 years
So, Hypothesis:
So, the value of test statistic would be
At α = 0.01 level of significance,
critical value z = 2.58
Since 2.58>0.471
so, We will accept the null hypothesis.
Hence, No, the average age is not higher than originally believed.
