<3= 83 (given)

<4=97

<5=83

<6=97

<7=83

<8=97

Step-by-step explanation:

They give you the angle for 3 which is 83, so from there all you have to do is find the equivalent angles which are angle 1,5,7. Then for angles 2,4,6,8 you subtract 83 from 180 and you get 97.

Assuming that it is known from previous studies that σ = 4.5 grams, how many mice should be included in our sample if we wish to

Yuki888 [10]

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

$z=\frac{x-\mu}{\sigma}$

Where, z value at 95% confidence interval is z=1.96

$\mu=3$ gram is the mean of the population

$\sigma=4.5$ gram is the standard deviation of the sample

Substituting the value, to find x sample mean

$1.96=\frac{x-3}{4.5}$

$1.96\times 4.5=x-3$

$8.82=x-3$

$x=8.82+3$

$x=11.82$

Therefore, The required amount of mice is 11.82 gram.
