We are interested in determining whether or not the variances of the sales at two music stores (A and B) are different. A sample of 26 days of sales at store A has a sample standard deviation of 20, while a sample of 16 days of sales from store B has a sample standard deviation of 30. What are the results of the hypothesis test at a significance level of 0.05?

If the maximum unambiguous velocity measurable by the pulsed Doppler system is 80 cm/s at an angle of 60°, which corresponds to a Doppler frequency shift of 4 kHz, what would be the required Pulse Repetition Frequency (PRF) for the system?
