In a random sample of 29 people, the mean commute time to work was 33.9 minutes and the standard deviation was 7.1 minutes. Assume the population is normally
distributed and use a t-distribution to construct a 90% confidence interval for the population mean u. What is the margin of error of p? Interpret the results.
The confidence interval for the population mean
(Round to one decimal place as needed)
is (L
)
The margin of error of his
(Round to one decimal place as needed)
Interpret the results
O A With 90% confidence, it can be said that the commute time is between the bounds of the confidence interval.
OB. It can be said that 90% of people have a commute time between the bounds of the confidence interval.
OC. With 90% confidence, it can be said that the population mean commute time is between the bounds of the confidence interval
OD. If a large sample of people are taken approximately 90% of them will have commute times between the bounds of the confidence interval

step-by-step explanation:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.

5x+10 is the correct one
