Please number your responses to the questions as they are shown (1 and 2). Tanya is given the graphs of the following functions. The functions f(x) and g(x) are linear, and the function s(x) is quadratic.
f(x) = 31 - 8
g(x) = -2x + 5
s(x) = 4x^2 - 9x + 2
Tanya is then asked to find the graph of (f. g)(x) and the graph of (g. s)(x). For each combined function, she is given four options to choose from.
1. What clues will help Tanya identify the correct graph of (f. g)(x)
2. What clues will help Tanya identify the correct graph of (g. s)(x)

Arandom sample of 15 observations is used to estimate the population mean. the sample mean and the standard deviation are calculated as 172 and 63, respectively. assume that the population is normally distributed. a. with 99 confidence, what is the margin of error for the estimation of the population mean? b. construct the 99% confidence interval for the population mean. c. construct the 95% confidence interval for the population mean. d. construct the 83% confidence interval for the population mean. hint: you need to use excel function =t.inv.2t to find the value of t for the interval calculation.
