Applied Project: You have been asked by the Census Bureau to gather info about the

age (in years) of the people in Virginia; The information gathered will be used to better

understand the distribution of ages so that key decisions can be made within the State.

You will need to obtain the ages ( in years) of at least 30 individuals.

Find the following statistic; mean, median, mode, midrange, range, standard

deviation, variance, sample size, and—quartiles.

Construct a frequency table, histogram, stem-&--leaf plot and-box—plot ' .

Include a table that lists class limits, class boundaries, frequency and relative frequency.

Construct 90%, 95% and 99% confidence intervals about the mean of your data

Assuming that we have a normal distribution, calculate the following probabilities

1. P(45<x<65)
2. P(x<20)
3. P(x>60)
4. P(18<X<40)

7. Previous information gathered by the Bureau shows that the average age of a

person in VA is \(\mu \) = 46 . Assuming a normal distribution

1. Use a 1% level of significance to test the claim that the average age of a person in VA is different from 46; use info from your sample. Explain the results.
2. Use a 5% level of significance to test the claim that the average age of a person in VA is greater than the claim of 46. Explain the results.

Problem : A brewery claims that the consumers are getting a mean volume equal to 32. ounces of beer in their quart bottles. The Bureau of Weights and Measures randomly selects 36 bottles and obtains the following measures in ounces:

Using the sample standard deviation as an estimate for \({{\sigma }_{X}}\) test the claim of the brewery

at the 0.05 significance level.
