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.

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
