An accountant for a large department store has the business objective of developing a model to predict the amount of time it takes to process invoices using the number of invoices processed. Data are collected from the past 32 working days, the number of invoices processed and completion time (in hours) are stored, and statistical analysis showed that the p-value of the test statistics was 0.46. What will be your null and alternative hypotheses

Null hypothesis: There is no relationship between the amount of time it takes to process invoices and the number of invoices processed.

Alternate hypothesis: There is a relationship between the amount of time it takes to process invoices and the number of invoices processed.  

Step-by-step explanation:

In statistics, the null hypothesis is used to state there is no relationship between two variables of interest. The implication of the null hypothesis in this question is that the amount of time it takes to process invoices cannot be predicted from the number of invoices processed.

In statistics, the alternate hypothesis is used to state there is a relationship between two variables of interest. Alternate hypothesis is the hypothesis that is accepted when the null hypothesis is rejected. The implication of the alternate hypothesis in this question is that the amount of time it takes to process invoices can be predicted from the number of invoices processed.

2 & 7

step-by-step explanation:

he climbs 300 ft/hr at a constant rate. the peak is at 1,500 ft.

when going up, he reaches 600 ft in 2 hours. remember, that he is going in a constant rate. divide 600 with 300:

600/300 = 2

assuming that he takes the same route back (meaning that it's a 1500 ft route back, you can solve.

note also that you are solving when he gets back to 600 ft after he reaches the peak.

first, find the amount of hours it takes to get up the peak. divide the total amount (1500), with the ft/her (300) to get the amount of hours (x):

1500/300 = x

x = 5

it takes jamie 5 hours to get up. now, he is returning down, and reaches 600 (his current destination). remember that he climbs at a constant 300 ft/hr. divide 600 with 300:

600/300 = x

x = 2

now add the two numbers together.

x = 5 + 2 = 7

jamie takes 7 hours to go up the mountain and reach his current position when descending.

(total amount/constant rate) = (time).

remember that it is a constant rate, so in total, when he gets back down the mountain, it will take the same amount of time as when he goes up. the total amount for the round trip is: 5 + 5 = 10.

its adding 5.5 each time
