The mouse weights (in grams) of a random sample of 100 mice involved in a nutrition experiment are: Interval 41.543.5 43.545.5 45.547.5 47.549.5 49.551.5 51.553.5 53.555.5 55.5 57.5 57.559.5 Frequency Interval 3 7 13 24 15 16 13 7 2Required:a. Find the mean of the weight of the mice. (Round to two decimal places.)b. Find the standard deviation of the weight of the mice. (Round to two decimal places.)

(a) The mean of the weight of the mice is 50.26 grams.

(b) The standard deviation of the weight of the mice is 14.08 grams.

Step-by-step explanation:

(a)

The mean is given as follows:

Thus, the mean of the weight of the mice is 50.26 grams.

(b)

Compute the standard deviation as follows:

Thus, the standard deviation of the weight of the mice is 14.08 grams.

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
