At wind speeds above 1000 cm/sec significant sand-moving events begin to occur. In particular, 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 sand dunes. At one test site, the prevailing direction of the wind did not change. However, the speed did change. Sixty wind speed readings gave an average speed of 1075 cm/sec. From long term experience, it can be assumed that = 265 cm/sec. a. Construct 95% confidence interval for the population mean wind speed at the test site. Show work by writing out the following: The given numbers with their corresponding variables. The formula that's used to calculate the lower and upper bounds. Which calculator program you used
