Answer #1

Correlation coefficient between Unemployment rate and High School degree=-0.5074

Correlation coefficient between Unemployment rate and Bachelor's=-0.03074

Correlation coefficient between High School degree and Bachelor's=-0.6687

We see that Correlation coefficient between Unemployment rate and High School degree is negative and its magnitude is moderate. Hence as High School degree increases Unemployment rate decreases. But strength of the correlation is not so good. However Correlation coefficient between Unemployment rate and Bachelor's is almost zero i.e. there is no relation between these two variables. Here we have also seen that the Correlation coefficient between High School degree and Bachelor's is negatively fair.

We wish to determine the impact of Specification Buying, X11, on Satisfaction Level, X10. To do so we will split the Hatco data file into two separate data sets based on the Specification Buying, X11. This variable has two categories: 1=employs total value analysis approach, evaluating each purchase separately; 0 = use of specification buying. Sort the entire Hatco data set based on Specification Buying. This will create two separate groups of records. Those records with X11 = 0 and...

An important statistical measurement in service facilities (such as restaurants and banks) is the variability in service times. As an experiment, two bank tellers were observed, and the service times for each of 100 customers were recorded. Do these data allow us to infer at the 5% significance level that the variance in service times differs between the two tellers? Estimate with 95% confidence the ratio of variances of the two bank tellers. Teller 1 Teller 2 7.2 10.9 5.4...
