Answer:
I don't see the picture
Step-by-step explanation:
25-4^2/8=
4^2= 16
16/8= 2
25-2=23
The answer to the first question is 23.
12*5-8/4+7*2=
12*5= 60
8/4= 2
7*2= 14
60-2+14= 72
The answer to the second question is 72.
Number one is 23.
Number two is 72.
Answer:
The confidence interval for the population mean μ is
Step-by-step explanation:
Given :
Number of weights of newborn girls n=185.
Mean hg
Standard deviation s=7.5 hg
Use a 95% confidence level i.e. cl=0.95
To find : What is the confidence interval for the population mean μ?
Solution :
Using t-distribution,
The degree of freedom
The t critical value is t=1.973.
The confidence interval build is
Substitute the values,
Therefore, the confidence interval for the population mean μ is
