Step-by-step explanation:
So, each day Tami's laps are 3 more than Kelly's. Why? Well, If you divide (on day two) 6 by 2 you get 3 and 3 laps is what Kelly had for that day. And for the table it looks like the number of laps completed multiplied by 2. Like, Tami's was 2 day and 6 laps. 3 day, 12 laps. Ask me if you need more help explaining. :)<span />
Answer:
p value is 0.1343
Step-by-step explanation:
Null: u>= 442
Alternative: u < 442
Using the formula for z score:
(x - u)/sd/√n
Where x is 438, u = 442 sd can be determined from the variance = √variance =√576 = 24 and n = 44
z score = 438-442 / (24/√44)
z score = -4/(24/6.6332)
z = -4/3.6182
z =-1.1055
Now let's find the p value at 0.1 significance level using a z score of -1.1055, using a p value calculator, p value is 0.1343 which greatest than 0.1 meaning the day is not sufficient enough to conclude that the machine is underfilling the bags.
