Arandom sample of 12 second-year university students enrolled in a business statistics course was drawn. at the course's completion, each student was asked how many hours he or she spent doing homework in statistics. the data are listed below. 515264595961635861505157 it is known that the population standard deviation is 6. the instructor has recommended that students devote 5 hours per week for the duration of the 12-week semester, for a total of 60 hours. test to determine whether there is evidence at the 0.025 significance level that the average student spent less than the recommended amount of time. fill in the requested information below.

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.

hey! so 1 (25) out of 4 (100) is 25 so your answer is 25%. it's like quarters!
