Answer:
x = 24 degrees
Step-by-step explanation:
You need to know, that one line has a total of 180 degrees. So, first solve for y by subtracting 180 - 103. You get 77. So y is 77 degrees. Now add 77 + 79 to get 156. Now subtract 180 - 156 to solve for x. You get 24 degrees.
Hope it helps!
Answer:
b. There is no difference between p1 and p2.
Step-by-step explanation:
Given that a 90% confidence interval for the difference of proportions contains some positive and some negative values
i.e. confidence interval lower bound is negative and upper bound is positive
This confirms that 0 is contained in the confidence interval for difference of proporitons at 90%
Hence for the hypotheses
we find that 0 is inside the confidence interval
This implies null hypothesis is accepted
Hence we conclude that there is no difference
b. There is no difference between p1 and p2.
100÷11=9.09090909
converting it it will be 9.1 miles per hour
