Answer:
a) 0.0167
b) 0
c) 5.948
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 6.16 ounces
Standard Deviation, σ = 0.08 ounces
We are given that the distribution of fill volumes of bags is a bell shaped distribution that is a normal distribution.
Formula:
a) Standard deviation of 23 bags
b) P( fill volume of 23 bags is below 5.95 ounces)
P(x < 5.95)
Calculation the value from standard normal z table, we have,
c) P( fill volume of 23 bags is below 6 ounces) = 0.001
P(x < 6) = 0.001
Calculation the value from standard normal z table, we have,
If the mean will be 5.948 then the probability that the average of 23 bags is below 6.1 ounces is 0.001.
For the first step you need to convert between feet in real life and feet in the cartoon drawing. 1/2 inch in cartoon is 3 feet in real life, so 1 foot in real life was 1/6 inch in cartoon. Her hair was 21 feet in real life, therefore it was 21/6, or 7/2 inches long in the cartoon. For the second step you need to explain what I just said, In your own words! Please do not simply copy down my solution.
Answer:
2:20PM
Step-by-step explanation:
3:45 - 1 hour = 2:45 (drive)
2:45 - 25 minutes = 2:20
2:20pm
Answer:
Now we can find the p value based in the alternative hypothesis and we got:
Step-by-step explanation:
Information given
represent the sample mean
represent the population standard deviation
sample size
represent the value to verify
z would represent the statistic
represent the p value
System of hypothesis
We want to verify if the true mean for this case is 64 or no, the system of hypothesis would be:
Null hypothesis:
Alternative hypothesis:
The statistic is given by:
(1)
The statistic for this case is given by:
Now we can find the p value based in the alternative hypothesis and we got:
