Answer:
Confidence interval: 11.5 < µ < 30.9
Read below to see conclusion:
Step-by-step explanation:
n = 13, x = 79.4, s = 21.2, Z = 1.645 (z score for a confidence interval with 90% confidence)
Use the formula to find the error: E = Z(s/√n)
We have: E = 1.645(21.2/√13) = 9.7
Now construct the confidence interval:
x - E < µ < x + E
21.2 - 9.7 < µ < 21.2 + 9.7
11.5 < µ < 30.9
Yes, the drug appears to be effective because the estimated wake time for a population using this drug will be between 11.5 and 30.9 minutes. The upper end of this interval is much lower than 102, so it appears as though the drug is effective.
