Read step by step explanation
Step-by-step explanation:
The owner already knows that the limit for the average time delivered pizzas is 38 minutes. So we conclude
1.-The resulting mean from sample data ( x ) ( 27 customers) need to be smaller than 38 minutes, any value of sample above 38 minutes means more time for the delivery action and will indicate a failure for the future project
2.-As sample size is smaller than 30 the test has to be t-student one tail test to the left
Test hypothesis
Null hypothesis H₀ x = 38
Alternative hypothesis Hₐ x < 38
We should test at a significance level α = 0,05 (α = 5%)
If the result of the test is to accept H₀ delivery project won´t be implemented, if on the other hand, H₀ is rejected then in the condition of the alternative hypothesis we accept Hₐ the sample indicates that we have a smaller average time than 38 minutes.
Answer:
1. $11.50 2a. 25 2b. Decrease by 10
Step-by-step explanation:
1. Let's write Marietta's wage before a raise as x
$12.25 = x + $0.75
$12.25 - $0.75 = x
x = $11.50
2a. Let's substitute p with the actual value ($170)
170 = 8n - 30
200 = 8n
n = 200/8 = 25
2b.
p = 8*25 - 40
p = 200 - 40 = 160
160 < 170 so the profit decreased
It decreased by 10 (170 - 160).
Answer:
Step-by-step explanation:

2) 342/3= 114 so 114 people
3) 558*7= 3906 so 3,906 marbles in total
4) 835/5 = 167 children per house
5) 156*12= 1872 so 1,872 apples
6) 138*92= 12696p or 126.96 pounds
7) 1276*8= 10208 matches
8) 2736/9= 304 sweets each
