<span>You are given volume of 6 US
quart. You are required to convert this into liters and be rounded off to the
nearest hundredth. Keep in mind that for
volume, every one liter is equal to 1.05669 US quart. So you need to divide the
6 US quart. This is equal to 6.34014 liters. To round of the nearest hundredth,
the ocation of the hundredth is the four in 6.3<u>4</u>014. since after four is
zero, the round off rule states that from 0-4, the preceding number remains
unchanged. So the final answer is 6.34 liters.</span>
Answer:
When we compare the significance level
we see that
so we can reject the null hypothesis at 10% of significance. So the the true mean is difference from 21 at this significance level.
Step-by-step explanation:
Data given and notation
represent the sample mean
represent the population standard deviation
sample size
represent the value that we want to test
represent the significance level for the hypothesis test.
z would represent the statistic (variable of interest)
represent the p value for the test (variable of interest)
State the null and alternative hypotheses.
We need to conduct a hypothesis in order to check if the average age of the evening students is significantly different from 21, the system of hypothesis would be:
Null hypothesis:
Alternative hypothesis:
The statistic is given by:
(1)
Calculate the statistic
We can replace in formula (1) the info given like this:
P-value
Since is a two sided test the p value would be:
Conclusion
When we compare the significance level
we see that
so we can reject the null hypothesis at 10% of significance. So the the true mean is difference from 21 at this significance level.
