Suppose that e(x 1 ) = μ, var(x 1 ) = 7, e(x 2 ) = μ, var(x 2 ) = 13, e(x 3 ) = μ, and var(x 3 ) = 20, and consider the point estimates ˆ μ 1 = x 1 3 + x 2 3 + x 3 3 ˆ μ 2 = x 1 4 + x 2 3 + x 3 5 ˆ μ 3 = x 1 6 + x 2 3 + x 3 4 + 2 (a) calculate the bias of each point estimate. is any one of themunbiased?

In one day there are too high tides into low tides and equally spaced intervals the high tide is observed to be 6 feet above the average sea level after six hours passed a low tide occurs at 6 feet below the average sea level in this task you will model this occurrence using a trigonometric function by using x as a measurement of time assume the first high tide occurs at x=0. a. what are the independent and dependent variables? b. determine these key features of the function that models the tide: 1.amplitude 2.period 3.frequency 4.midline 5.vertical shift 6.phase shift c. create a trigonometric function that models the ocean tide for a period of 12 hours. d. what is the height of the tide after 93 hours?

Suppose babies born after a gestation period of 32 to 35 weeks have a mean weight of 25002500 grams and a standard deviation of 800800 grams while babies born after a gestation period of 40 weeks have a mean weight of 27002700 grams and a standard deviation of 385385 grams. if a 3232-week gestation period baby weighs 21252125 grams and a 4040-week gestation period baby weighs 23252325 grams, find the corresponding z-scores. which baby weighs lessless relative to the gestation period?
