Answer:
huhh what this is question is too hard
The best approximation for sqrt 55 would be: B) 7 2/5
Answer:
a. 5.26
Step-by-step explanation:
As, the standard deviation of the distribution of the difference between mean is 0.76 so the t score will be simply calculated by dividing the difference of means by standard deviation of the distribution of the difference between mean as hypothesized difference is zero.
t score=Xbar A- Xbar B/Sd of difference of means
t score=55-51/0.76
t score=4/0.76=5.26
B= What’s the question. Maybe try looking at math-way
Answer:
90? He score for the class fast and easy
