Which question do you need help with
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
Answer:
$28360
Step-by-step explanation:
Step one:
Given data
P=20000
rate= 6%
time= 6years
Step two:
compound interest
A=P(1+r)^t
substitute
A=20000(1+0.06)^6
A=20000(1.06)^6
A=20000*1.418
A=$28360
