At the Olympic games, many events have several rounds of competition. One of these events is the men's 100100100-meter backstrok
e.
The upper dot plot shows the times (in seconds) of the top 888 finishers in the final round of the 201220122012 Olympics. The lower dot plot shows the times of the same 888 swimmers, but in the semifinal round.
Which pieces of information can be gathered from these dot plots? (Remember that lower swim times are faster.)

Answer:
Hence the 90% confidence interval estimate of the population mean is
Step-by-step explanation:
Given that,
Point estimate = sample mean = = 88.34
sample standard deviation = s = 19.22
sample size = n = 14
Degrees of freedom = df = n - 1 = 13
Critical value = df = 1.771
Margin of error
Margin of error = E = 9.10
The 90% confidence interval estimate of the population mean is,
Answer:
9.19 mi. is the distance between Bank and Grocery store.
Step-by-step explanation:
As we know in a given triangle with sides a, b, c which are the opposite sides of ∠A, ∠B, ∠C, follow the property
Now we apply this property in the given triangle.
Let the distance between Grocery store and Bank = x mi
So the answer is 9.19 mi.
