Answer:
The test statistic is z = 1.865.
Step-by-step explanation:
The test statistic is:
In which X is the sample mean, 
is the value tested at the null hypothesis, 
is the standard deviation and n is the size of the sample.
H0: p = 0.11
This means that 0.11 is tested at the null hypothesis, and so:
The engineer weighs 94 bags and finds that 16 of them are over-filled.
This means that:
What is the test statistic?
The test statistic is z = 1.865.
Answer:
She should have multiplied by 10,000
Step-by-step explanation:
Given table:
To find the conversion rate:
Therefore, 1 hectogram = 10,000 centigrams
So when converting hectograms to centigrams, multiply the mass by 10,000.
⇒ 50 hg × 10,000 = 500,000 centigrams
Rachel's error was that she should have multiplied by 10,000.
Answer:
-63
Step-by-step explanation:
This arithmetic progression
The formula is a+(n-1)d
a means the first value
n is the nth term
d is the difference
So a is -5
n is 30
d is -2
So let's substitute
-5+(30-1)-2
-5+(29)-2
-5-58
-63
Therefore the final answer is-63
Just follow the step and the general formula, you will get your final answer
The answer is 223.75 because you multiply 12.5 and 17.9
