Question

The sample mean is Greater/Less than the previous mean, so, on average, consumption from the sample is Greater/Less than in the previous study. The sample standard deviation is Greater/Less than the previous standard deviation by _____ so the milk consumption is More/Less spread out in the sample.

Above is the complete question for the last question of the problem that I attached below.

You are performing a study about weekly per capita milk consumption. A previous study found weekly per capita milk consumption to be normally distributed, with a mean of 47.4 fluid ounces and a standard deviation of 11.1 fluid ounces. You
randomly sample 30 people and record the weekly milk consumptions shown below.

C. No, because the histogram is neither symmetric nor bell-shaped.
D. No, because the histogram is symmetric and bell-shaped.
(b) Find the mean of your sample.
The mean is.
(Round to one decimal place as needed.)
Find the standard deviation of your sample.
The standard deviation is
(Round to one decimal place as needed.)
(c) Compare the mean and standard deviation of your sample with those of the previous study. Discuss the differences.
The sample mean is
than the previous mean, so, on average, consumption from the
sample is
than in the previous study. The sample standard deviation is
than the previous standard deviation by
so the milk consumption is
spread out in the sample.

Definition Definition Measure of central tendency that is the average of a given data set. The mean value is evaluated as the quotient of the sum of all observations by the sample size. The mean, in contrast to a median, is affected by extreme values. Very large or very small values can distract the mean from the center of the data. Arithmetic mean: The most common type of mean is the arithmetic mean. It is evaluated using the formula: μ = 1 N ∑ i = 1 N x i Other types of means are the geometric mean, logarithmic mean, and harmonic mean. Geometric mean: The nth root of the product of n observations from a data set is defined as the geometric mean of the set: G = x 1 x 2 ... x n n Logarithmic mean: The difference of the natural logarithms of the two numbers, divided by the difference between the numbers is the logarithmic mean of the two numbers. The logarithmic mean is used particularly in heat transfer and mass transfer. ln x 2 − ln x 1 x 2 − x 1 Harmonic mean: The inverse of the arithmetic mean of the inverses of all the numbers in a data set is the harmonic mean of the data. 1 1 x 1 + 1 x 2 + ...
