Answer:
The required amount of mice is 11.82 gram.
Step-by-step explanation:
Given : Assuming that it is known from previous studies that σ = 4.5 grams. If we wish to be 95% confident that the mean weight of the sample will be within 3 grams of the population mean for all mice subjected to this protein diet.
To find : How many mice should be included in our sample?
Solution :
The formula used in the situation is

Where, z value at 95% confidence interval is z=1.96
gram is the mean of the population
gram is the standard deviation of the sample
Substituting the value, to find x sample mean





Therefore, The required amount of mice is 11.82 gram.
1/3+9=(9 1/3)
8-3= (5)
9*5=45 add the 1/3 back in
45 1/3 for the fraction take 45*3=135+1= 136/3
136/3 is the answer
6 13/50 as a decimal is 6.26
Hope this helps
