It is because both the dividend and the divisor are multiplied by 10, 100, 1000, or some other power of ten.
Answer:
The 90% confidence interval for the population standard deviation waiting time for an oil change is (3.9, 6.3).
Step-by-step explanation:
The (1 - <em>α</em>)% confidence interval for the population standard deviation is:
The information provided is:
<em>n</em> = 26
<em>s</em> = 4.8 minutes
Confidence level = 90%
Compute the critical values of Chi-square as follows:
*Use a Chi-square table.
Compute the 90% confidence interval for the population standard deviation waiting time for an oil change as follows:
Thus, the 90% confidence interval for the population standard deviation waiting time for an oil change is (3.9, 6.3).
Answer:
She rode her bike 20 miles... I believe this may be a trick question.
Step-by-step explanation:
Let's break down this problem...
If she is going at a rate of 5 miles per hour while walking than the maximum she could have walked in 5 hours is 25 miles.
If Angela rode her bike for 20 miles, and the got off her bike and walked "<em>the rest of the way</em>" then she should have walked 50 miles. However as we already know her rate is 5 miles per hour while walking, and therefore could only have covered half that distance in 5 hours.
Is this a multiple choice question? Is there any misssing informaation?
