Answer:
The probability that the sample mean will lie within 2 values of μ is 0.9544.
Step-by-step explanation:
Here
- the sample size is given as 100
- the standard deviation is 10
The probability that the sample mean lies with 2 of the value of μ is given as
Here converting the values in z form gives
Substituting values
From z table
So the probability that the sample mean will lie within 2 values of μ is 0.9544.
Answer:
the data of the cubic
as it the distance between the two integers closed under addition
All you have to look at is the word "dropped" and you know it's a subtraction problem. In this case, it would be 8 - 15.
8 - 15 = -7
It would be -7<span>°C at midnight. I hoped this helped! :)</span>

b) 2012, 1049 stores. 2014, 1041 stores. c) Yes it is a downsizing company.
Step-by-step explanation:
a)
s=year | f(s) = number of stores per year
1 | 1078
4| 1067
s=1 in 2003
b) For 2012, s=9. For 2014, s=11
c) In deed. Since the function shows a decreasing amount of JC Penney stores. Maybe this is a downsizing from this company, progressively closing some stores.
