A random sample of n measurements was selected from a population with unknown mean u and standard deviation o d.Calculate a 95% confidence interval for u for each of these situations. 20 for each of the situations in parts a through a. n = 60, x 32 b.n 200, x 119 C.n=90, x 13 d. n 90, x 4.59 e. Is the assumption that the underlying population of measurements is normally distributed necessary to ensure the validity of the confidence intervals in parts a through d? Explain. a.

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.
