A farmer believes that the average pumpkin from his crop weighs at least 7 pounds. To test his claim, he selects 15 pumpkins randomly and weighs them. The weights (in pounds) are listed below:

4.8 7.8 5.9 10.1 7.2 8.1 6.0 9.3 6.7 4.3 8.3 6.9 10.0 9.2 6.8

The sample statistics are: ?̅= 7.43, ? = 1.77

Can the farmer infer, at the 5% significance level, that his claim is true? Assume the required conditions are satisfied.

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...

Med Student Sleep Average (Raw Data, Software Required): Here we consider a small study on the sleep habits of med students and non-med students. The study consists of the hours of sleep per night obtained from 30 non-med students and 25 med students. The sample data is given in the table below. Test the claim that, on average, the mean hours of sleep for all med students is different from that for non-med students. Test this claim at the 0.01...

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...

To measure profitability, La Quinta used operating margin, which is the ratio of the sum profit, depreciation, and interest expenses divided by total revenue. The ratio is expressed in percent form, meaning that it could theoretically take on any value between 0 and 100, with a higher value indicating greater profitability. La Quinta defines profitable inns as those with an operating margin in excess of 50 percent; unprofitable inns are those with margins of less than 30 percent. After a...
