Answer:
its the one in the bottom left corner!
Step-by-step explanation:
all are congruent
Answer:
t = [ (x1' - x2' ) - d ] / SE . p < 0.05 suggests means are equal, p > 0.05 suggests means are unequal.
Step-by-step explanation:
Null Hypothesis [H0] : There is no difference between average estimates of two garages, M1 = M2
Alternate Hypothesis [H1] : There is difference between average estimates of two garages, M1 ≠ M2
Hypothesis can be tested by t test
t = [ (x1' - x2' ) - d ] / SE , where :-
x1' & x2' are sample means, SE = sqrt[ (s1^2/n1) + (s2^2 /n2) ] , d is the hypothesized difference between population means, and SE is the standard error ie 0 here
If the p value corresponding to calculated t value is < p value as per significance level (0.05) : We reject null hypothesis & state that M1 ≠ M2
If the p value corresponding to calculated t value > p value as per significance level (0.05) : We accept null hypothesis & state that M1 = M2
Answer:
x= 45 degrees
Step-by-step explanation:
the top angle is a eight angle which is equal to 90 all triangles are 180 degrees both bottom angles are equal and 180 minus the 90 degree from the right angle is 90 degrees you divide that by 2 and you have your answer
