P(bull's-eye) = 700/30000 x 100% = 2.33% ≈ 2%
option A is the correct answer.
Answer:
Step-by-step explanation:
<u>Let the price before tax be x, then we have:</u>
- x + 8% = 372.60
- x + 0.08x = 372.60
- 1.08x = 372.60
- x = 372.60 / 1.08
- x = 345
The initial price was $345
Answer:
The 95% confidence interval = (98.225, 98.655)
Step-by-step explanation:
The formula for Confidence Interval =
Mean ± z × standard deviation/√n
Where Mean = 98.44°F
Standard deviation = 0.30°F
n = number of samples is 10
Because our number if samples is small, we use the t score confidence interval formula
Mean ± t × standard deviation/√n
Degrees of Freedom = n - 1
= 10 - 1 = 9
We find the t score of 95% confidence interval and degrees of freedom 9
= 2.262
Hence,
Confidence interval = 98.44 ± 2.262 × 0.30/√10
= 98.44 ± 0.214592162
Confidence Interval
98.44 - 0.214592162
= 98.225407838
≈ 98.225
98.44 + 0.214592162
= 98.654592162
≈ 98.655
The 95% confidence interval = (98.225, 98.655)
