Answer:
The test statistic for Norah's test is
Step-by-step explanation:
Norah is in charge of a quality control test that involves measuring the amounts in a sample of bottles to see if the sample mean amount is significantly different than 500 ml.
This means that at the null hypothesis we test if the sample mean is 500 ml, that is:
At the alternate hypothesis, we test if it is differente than 500 ml, that is:
The test statistic is:
In which X is the sample mean, is the value tested at the null hypothesis, s is the standard deviation of the sample and n is the size of the sample.
500 is tested at the null hypothesis:
This means that
She takes a random sample of 16 bottles and finds a mean amount of 497ml, and a sample standard deviation of 6ml.
This means that
Calculate the test statistic for Norah's test.

Hi friend!
Answer: Tyler used the distributive property.
Here, First of all, you need to calculate the LCM of 12, 15, 20 & 35
LCM of 12, 15, 20 & 35 is 420
Now, We know, smallest 4-digit number is 1000,
Divide, 420 from 1000, It cuts on 840 (with quotient 2),
So, we need next term, in order to know, just add another 420 to 840, which is:
840 + 420 = 1260
In short, Your Answer would be 1260
Hope this helps!
