The owners of the Franklin Park Mall are studying the shopping habits of their customers. From earlier studies the owners are under the impression that a typical shopper spends 0.75 hours at the mall. Recently the mall owners have added some specialty restaurants designed to keep shoppers in the mall longer. A consulting firm has been hired to evaluate the e↵ects of restaurants. A sample of n = 45 shoppers was selected and revealed the sample mean time spent in mall of ¯x = 0.80 hours and the sample standard deviation of s = 0.10 hours. (a) Use ↵ = 0.01 and conduct a hypothesis test H0 : µ = 0.75 versus Ha : µ > 0.75 (b) Interpret your answer in part (a).

step-by-step explanation:

square root of 36/6 = 2.449489743

square root of 16/6 = 1.632993162

square root of 6 = 2.449489743

the answer is square root of 16/6 because the square root of 36/6 is the same answer as square root of 6 = 2.449489743

i’ll just s take the points thxs

1. 180°. the sum of the interior angles of a triangle is 180°, for the equilateral triangle that it has three equals side is 60°+60°+60°=180°.

2. 60°. each interior angle of a equilateral triangle is 60°

3. 120°. the measure of ∠m is 120°, the sum of the angles ∠m and ∠n is equal to 180°. so, in order to find the measure of ∠m, we have ∠m+∠n=180° > ∠m=180°-∠n > ∠m=180°-60°=120°.

4. 360°. the sum of the exterior angles of an equilateral triangle is ∠m+∠r+∠x=120°+120°+120°=360°. the exterior angles of any triangle always add 360°.
