(a) If x is distributed as x - N (46, 50) and samples of size n = 35.00 are drawn, what is the distribution of the sample mean x? (b) If the sample size doubled to 70, how is the standard error(SE) of x altered? (c) Using the sample size of 35.00, (i) what is P(x>48) ?, (ii) what is P(x< 45)?, and (iii) what is P(45.5 48) = % (Round the final answer to two decimal places as needed.) (ii) P(x< 45) =% (Round the final answer to two decimal places as needed.) (ii) P (45.5 < x <48) = % (Round the final answer to two decimal places as needed.)

Equations and Inequations
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.
