Late delivery ~ Amazon wants to maintain the existing customer loyalty. Initial data analysis revealed that the proportion of orders that are delivered late to the customers is 0.102. They take measures to improve the quality of their delivery service. Alexa wants to determine if the actual proportion of orders that are delivered late to the customers is different from the value reported by the initial data analysis. In a recent random sample of 191 orders, Alexa found that 13 orders are delivered late. A normal distribution is used to carry out the following hypothesis test: H0:p= 0.102 vs HA:p≠ 0.102. What is the test statistic for this hypothesis test?

idk

step-by-step explanation:

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
