Let p denote the probability that, for a particular tennis player, the first serve is good. Since p = 0.4, this player decided to take lessons in order to increase p. When the lessons are completed, the hypothesis Ho : p= 0.40 is tested against H1 : p> 0.4 based on n= 25 trials. Let y equal the number of first serves that are good, and let the critical region be defined by C = {y: y 2 13}. Determine a = P(Y > 13; p= 0.40) and Find B = P(Y < 13) when p= 0.60; that is, 3 = P(Y < 12; p= 0.6) so that 1-3 is the power at p= 0.60. %3D

Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
Question

Please see attached mathematical statistics question. How to determine alpha = P(Y >= 13; p = 0.40) and find B = P(Y < 13) when p = 0.60; that is, B = P(Y <= 12; p = 0.6) so that 1 - B is the power at p = 0.60?

on n = 25 trials. Let y equal the number of first serves that are good, and let the critical
region be defined by C = {y : y 2 13}.
Determine a = P(Y > 13; p = 0.40) and Find 3 = P(Y < 13) when p = 0.60;
that is, 3 = P(Y < 12; p = 0.6) so that 1-3 is the power at p = 0.60.
