Question

A study on the latest fad diet claimed that the amounts of weight lost by all people on this diet had a mean of 23.6 pounds and a standard deviation of 7.0 pounds. Step 1 of 2 : If a sampling distribution is created using samples of the amounts of weight lost by 61 people on this diet, what would be the mean of the sampling distribution of sample means? Round to two decimal places, if necessary.

Answer #1

Solution :

Given that,

mean = = 23.6

standard deviation = = 7.0

n = 61

_{}
=
= 23.6

_{}
=
/
n = 7.0 /
61 = 0.90

A powder diet is tested on 49 people, and a liquid diet is
tested on 36 different people. Of interest is whether the liquid
diet yields a higher mean weight loss than the powder diet. The
powder diet group had a mean weight loss of 42 pounds with a
standard deviation of 12 pounds. The liquid diet group had a mean
weight loss of 45 pounds with a standard deviation of 14
pounds.

Suppose that a study of elementary school students reports that
the mean age at which children begin reading is 5.4 years with a
standard deviation of 0.7 years.
Step 2 of 2:
If a sampling distribution is created using samples of the ages
at which 37 children begin reading, what would be the standard
deviation of the sampling distribution of sample means? Round to
two decimal places, if necessary.
