Chapter 8: Q. 58 (page 480)

The data in the Table are the result of a random survey of 39national flags (with replacement between picks) from various countries. We are interested in finding a confidence interval for the true mean number of colors on a national flag. Let X=the number of colors on a national flag.

Construct a localid="1648450905983" 95%confidence interval for the true mean number of colors on national flags.

Fill in the blanks on the graph with the areas, the upper and lower limits of the Confidence Interval and the sample mean.

Short Answer

Expert verified

We know that the mean number of colors on national flags was 3.26, lower and upper limits of the confidence interval were 2.93 and 3.59, respectively.

Using the same p′ and level of confidence, suppose that n were increased to 100. Would the error bound become larger

or smaller? How do you know?

The Ice Chalet offers dozens of different beginning iceskating classes. All of the class names are put into a bucket. The 5 P.M., Monday night, ages 8 to 12, beginning ice-skating class was picked. In that class were 64 girls and 16 boys. Suppose that we are interested in the true proportion of girls, ages 8 to 12, in all beginning ice-skating classes at the Ice Chalet. Assume that the children in the selected class are a random sample of the population.

Calculate the following:

a. x = _______

b. n = _______

c. p′ = _______

Construct a 95%confidence interval for the true mean number of colors on national flags.

The 95%confidence interval is_____.

A sample of 20heads of lettuce was selected. Assume that the population distribution of head weight is normal. The weight of each head of lettuce was then recorded. The mean weight was 2.2pounds with a standard deviation of 0.1pounds. The population standard deviation is known to be 0.2pounds.

What would happen if 40 heads of lettuce were sampled instead of 20, and the confidence level remained the same?

What will happen to the confidence interval obtained, if 500 newborn elephants are weighed instead of 50? Why ?
