I don't know how to solve
1 answer:
The answer would be 29* because the two measurements should be equal to 180*. So the value of one angle plus the value of the other angle equal 180. You gather all like values in the equation, then leave the x by it self by dividing. After you have the final x value, you substitute x to the initial values to give the final angle results.

Answer:
34.6= b
Step-by-step explanation:
a^2 + b^2 =c^2
13^2+b^2= 37^2
169+b^2= 1369
-169 -169
b^2 = 1200
b= 34.6
Using the t-distribution, as we have the standard deviation for the sample, it is found that there is a significant difference between the wait times for the two populations.
<h3>What are the hypothesis tested?</h3>At the null hypothesis, we test if there is no difference, that is:
At the alternative hypothesis, it is tested if there is difference, that is:
For each sample, we have that:
For the distribution of differences, we have that:
It is given by:
In which is the value tested at the null hypothesis.
Hence:
Considering a one-tailed test, as stated in the exercise, with 100 - 1 = 99 df, using a t-distribution calculator, the p-value is of 0.014.
Since the p-value is less than the significance level of 0.05, it is found that there is a significant difference between the wait times for the two populations.
