In a random sample of ​people, the mean driving distance to work was miles and the standard deviation was miles. Assume the popu

lation is normally distributed and use the​ t-distribution to find the margin of error and construct a ​% confidence interval for the population mean . Interpret the results. Identify the margin of error. nothing ▼ square miles miles per hour miles ​(Round to one decimal place as​ needed.) Construct a ​% confidence interval for the population mean. ​(Round to one decimal place as​ needed.) Interpret the results. Select the correct choice below and fill in the answer box to complete your choice. ​(Type an integer or a decimal. Do not​ round.) A. nothing​% of all random samples of people from the population will have a mean driving distance to work​ (in miles) that is between the​ interval's endpoints. B. It can be said that nothing​% of the population has a driving distance to work​ (in miles) that is between the​ interval's endpoints. C. With nothing​% ​confidence, it can be said that most driving distances to work​ (in miles) in the population are between the​ interval's endpoints. D. With nothing​% ​confidence, it can be said that the population mean driving distance to work​ (in miles) is between the​ interval's endpoints.

Colin and Brian were playing darts. Colin scored 91. Brian scored 9 more than Colin. What was their combined score?
Sloan [31]
Answer:
The combined score was 191
Explanation:
91 (Colin’s score) + 9 (how many more Brian had than Colin) = 100 (Brian’s score)
91 (Colin’s score) + 100 (Brian’s score) = 191 (combined score)
