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.
Answer:
- (-3, 5), (4, 1), (-1, -5)
Step-by-step explanation:
270° counterclockwise rotation is same as 90° clockwise
<u>The rule is:</u>
- (x, y) → (y, -x)
<u>Given points:</u>
- A(-5, -3), B(-1, 4), C(5, -1)
<u>Translated points:</u>
- A' = (-3, 5)
- B' = (4, 1)
- C' = (-1, -5)
