<span>(a) 2.09302406
(b) Lower limit of 95% confidence interval = 185.85
(a) To get the t-score, first determine the number of degrees of freedom you have. That's simply the number of samples minus 1, so in this case we have 19 degrees of freedom. Then calculate (1-0.95)/2 = 0.05/2 = 0.025 which is the size of the tail for the confidence interval you want. Finally, lookup in a T-Distribution Table for the 19 degrees of freedom and tail size. The value looked up will be 2.09302406.
(b) Once you have the t-score, to calculate your desired interval, calculate the following:
V = T*SD/sqrt(n)
where
V = Variance
T = T-score
SD = Standard deviation
n = number of samples
So let's plug in the values and calculate V
V = T*SD/sqrt(n)
V = 2.09302406*21.02/sqrt(20)
V = 2.09302406*21.02/4.472135955
V = 43.99536574/4.472135955
V = 9.837662849
Your 95% confidence interval is now the mean +/- V. So
lower limit = 195.69 - 9.84 = 185.85
upper limit = 195.69 + 9.84 = 205.53</span>
Answer:
A = 5t +7000
Step-by-step explanation:
Tim's rate of increasing altitude is 5 ft/min, so his change in altitude in t minutes is 5t.
If he started at 7000 ft, his altitude as a function of time is the sum of his initial altitude and his change in altitude:
A = 5t +7000
FIrstly, distribute 4 so that it multiplies with 6x and -11: 
Next, add 44 on both sides: 
Lastly, divide both sides by 24 and <u>your answer will be 
</u>
