The accounting at geico notices that the average claim might be larger than $1800, which was previously set as a true average claim amount.

if the actual average is higher, the company will be loosing money in the long run. they ran domly select 45 claims, and calculate a sample mean of s1,920.

suppose that the variance of claims is known to be equal to s1600.

(a) set the significance level to α 0.05 and use the hypothesis testing to check if the average claim is larger than $1800.

(b) find the probability of type i error.

(c) find the p-value corresponding to the given sample.

The function f(x) = 14,600(1.1)* represents the population of a town x years after it was established. what was the original population of the town?

Write the equation of a line that is perpendicular to the given line and that passes through the given point. –3x – 6y = 17; (6, 3) y = x – 9 y = 2x – 9 y = –2x – 9 y = x + 0 3. is the relationship shown by the data linear? if so, model the data with an equation. x y 1 5 5 10 9 15 13 20 the relationship is linear; y – 5 = (x – 1). the relationship is not linear. the relationship is linear; y – 5 = (x – 1). the relationship is linear; y – 1 = (x – 5). write an equation in point-slope form for the line through the given point with the given slope. (–10, –1); m = y + 10 = (x + 1) y – 1 = (x – 10) y – 1 = (x + 10) y + 1 = (x + 10) 5. write an equation for each translation of . 6.5 units up y + 6.5 = | x | y = | 6.5 x | y = | x | + 6.5 y = | x | – 6.5 6. write an equation for each translation of . 5.5 units right y = | x | + 5.5 y = | x – 5.5 | y = | x | – 5.5 y = | x + 5.5 | 7. which equation translates y = | x | by 8 units to the left? y = | x | – 8 y = | x | + 8 y = | x – 8| y = | x + 8|
