1. A survey found that the average hotel room rate in new orleans is 88.42 and the average room rate in phoenix is 80.61. Assume that the data was obtained from two samples of 50 hotels each and that the standard deviations were 5.62 and 4.83 respectively. At alpha=.05, so it can be concluded that there is a significant difference in rates?
2. Find the critical value for a right-tailed F-test when alpha=.05 the degrees of freedom for the numerator (d.f.N.) are 15, and the degrees of freedom for the denominator (d.f.N.) are 21.
3.Find the critical value for a two tailed F-test with alpha=.05 when the sample size from which the variance for the numerator was obtained was 21 and the sample size from which the variance for the denominator was obtained 12
A statistical analysis of 1,000 long-distance calls made from the headquarters of the Bricks and Clicks Computer Corporation indicates that the length of these calls is normally distributed with μ = 240 seconds and σ = 40 seconds.
If the 95% confidence interval for the average age of a learner at Capella is 27.8 yrs.

Determine payback period for implementing Oracle Discoverer? Assume that WebFocus will be in-place until December 31 and the migration to Oracle will be done concurrently and is expected to be completed and operational by Dec 31 as well.
One use of the Chi-square goodness of fit test is to determine if specified multinominal probabilities in the null hypothesis is correct.

Hugger Polls contends that an agent conducts a mean of 53 in-depth home surveys every week. A streamlined survey form has been introduced, and Hugger wants to evaluate its effectiveness.
What are the null and alternative hypothesis for this? What is a type II error in context of this test? Suppose that the researcher deceides not to reject the null hypothesis what sort of error might he be making?
Bill calculates a linear correlation coefficient between two variable as 1.20. How would you interpret this?
