. At wind speeds above 1000 cm/sec, significant sand–moving events begin to occur. Wind speeds below 1000 cm/sec deposit sand and wind speeds above 1000 cm/sec move sand to new locations. The cyclic nature of wind and moving sand determines the shape and location of large dunes. At a test site, the prevailing direction of the wind did not change noticeably. However, the velocity did change. 75 wind speed readings gave an average velocity of x =1045 cm/sec. Based on long–term experience,  can be assumed to be 240 cm/sec Find a 99% confidence interval for the population mean wind speed at this site.

4. While visiting Newfoundland, Ray notices that that the water level at a town dock changes during the day as the tides come in and go out. Marking on one of the piles supporting the dock show a high tide of 3.3 m at 6:30 am., a low tide of 0.7 m at 12:40 p.m., and a high tide again at 6.50 pm. a) Estimate the period of the fluctuations in the water level at the town dock. b) Estimate the amplitude of the pattern. c) Sketch the function.
