To find the number of years between 1844 to 2015 you have to subtract.
Lets say that x is the # of years in between 1844 and 2015
Then we have:
After doing the subtraction using a calculator or a pencil and paper, you get that:
So 171 years have passed from 1844 to reach to 2015.

Answer:
The degrees of freedom are:
Now we can calculate the p value using the alternative hypothesis:
Since the p value is higher than the signficance level assumed of 0.05 we have enough evidence to FAIL to reject the null hypothesis and there is no evidence to conclude that the true deviation differs from 0.12 ounces
Step-by-step explanation:
Assuming the following data:"12.14 12.05 12.27 11.89 12.06
12.14 12.05 12.38 11.92 12.14"
We can calculate the sample deviation with this formula:
represent the sample size
represent the confidence level
represent the sample variance
represent the value to verify
Null and alternative hypothesis
We want to determine whether the standard deviation differs from 0.12 ounce, so the system of hypothesis would be:
Null Hypothesis:
Alternative hypothesis:
The statistic can be calculated like this;
The degrees of freedom are:
Now we can calculate the p value using the alternative hypothesis:
Since the p value is higher than the signficance level assumed of 0.05 we have enough evidence to FAIL to reject the null hypothesis and there is no evidence to conclude that the true deviation differs from 0.12 ounces
