Answer:
The critical value is T = 3.143.
Step-by-step explanation:
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 7 - 1 = 6
98% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 6 degrees of freedom(y-axis) and a confidence level of
. So we have T = 3.143.
The critical value is T = 3.143.
Answer:
X= 25, the second one is 22, the third one is 19
y=20, the second one is 17, the thirst one is 12
The terms in patten y is 5 less than the terms in pattern x
Step-by-step explanation:
24000 + 3000x = 30000 + 2400x
3000x - 2400x = 30,000 - 24,000
600x = 6000
x = 6000/600
x = 10 years
