If x bar =75, S = 24, and n = 36, and assuming that the population is normally distributed, construct a 95% confidenceinterval estimate of the population mean, ยต.

A) SPSS and Data Summary: From the dataset attach, select any two quantitative variables. What is the name of your two quantitative variables you will be analyzing? Use SPSS to compute summary (descriptive) statistics, including measures of centraltendency mean, median, mode and numerical measures variance and standard devia

A sample of 144 cans of coffee showed an average weight of 16 ounces. The standard deviation of the population is known to be 1.4 ounces.
a. Construct a 68.26% confidenceinterval for the mean of the population.
b. Construct a 97% confidenceinterval for the mean of the population.

You are constructing a 95% confidenceinterval using the information: n = 60, = 65.5, s = 2.5, and E = 0.7. What is the value of the middle of the interval?
A. 0.7
B. 2.5
C. 0.95
D. 65.5
What sample size would be needed to estimate the population mean to within one-half standard deviation with 95% confidence?

In order to decide which measure of centraltendency is appropriate, you must first determine
a. The appropriate graph to use and the independent variable
b. The independent and dependent variables.
c. How the data will be collected
d. The scale of measurement being used and the shape of the distruibuion.
