It’ll be D) 7/46 you can reduce it by dividing everything with 4
Answer:
Check the explanation
Step-by-step explanation:
Going by the first attached image below we reject H_o against H_1 if obs.
here obs.T=1.879
we accept 
at 5% level of significance.
i.e there is no sufficient evidence to indicate that the special study program is more effective at 5% level of significance.
1.
this problem is simillar to the previous one except the alternative hypothesis.
Let X_i's denote the bonuses given by female managers and Y_i's denote the bonuses given by male managers.
we assume that 
independently
We want to test 
define 
now 
the hypothesis becomes
in the third attached image, we use the same test statistic as before
i.e at 5% level of significance there is not enough evidence to indicate a difference in average bonuses .
Answer:
No, although the random and large counts conditions are met, the 10% condition is not met.
Step-by-step explanation:
The random condition is met because the student selects a random sample of 50 seniors. The large counts condition is met because there are 38 expected successes and 12 expected failures, which are both at least 10. The 10% condition is not met because n = 50 is not less than 10% of the size of the population (N = 274 seniors).
Answer:
If a parallelogram has at least one 90 degree angle then its opposite angle is equal and also = 90 degrees.
The 2 remaining opposite angles add up to 180 degrees and since they must be equal, they must be 90 degrees each.
So, we have a quadrilateral with four 90 degree angles and is therefore a rectangle OR it could possibly be a square.
