According to the null hypothesis, a sample of 11 scores was drawn from a normal population with with a mean of 1969 and a standard deviation of 3. If the sample mean is 1969.7, calculate p for zobs assuming H1: H1 - Ho > 0. If Ho = 19, M1 = 21, Om = 5, and mcritical = 27.23, calculate S for H1: M1 - Ho > 0. Calculate the value of Us that corresponds to p1 = 19.39, Ho = 19.18 and o = 4. If I draw a sample of 3 scores from a normal distribution with a mean of u = 10, what is the probabilit that t = (m - p)/Sm will fall in the interval 12? Determine the sample size required to achieve power = .98, assuming Ho = 11, o = 4, and H1: H1 - Ho > 0, for a = .03 and 8 = .751. Please round your answer UP to the nearest whole number
