Iam very confused so i'm doing a worksheet for algebra 1 (highschool) and we're doing division and multiplication with fractions at the moment to review what we learned last year and i'm stuck. right now i'm doing #1 and ended up getting 7 so i ended up doing this as my equation..i have no idea if i'm supposed to do division with this but i tried division and multiplication and got 7 1\2 everytime i did it. and i know the answer is 1 7/8 cause i may have found a cheat sheet online but i still need to know how to do it. anyways this is what i did: i don't understand what i'm doing wrong lol.

Which statements are true about box plots? check all that apply. they describe sets of data. they include the mean. they show the data split into four parts. they show outliers through really short “whiskers.” each section of a box plot represents 25% of the data.

Anull hypothesis states that the difference between 8 hours of sleep and 3 hours of sleep has no effect on the number of pictures a student will remember during a picture memory interface test (pmit). examining the mit database, an extremely small t-value of 0.1611 is found. this t-value is much smaller than the smallest t-value on the chart for p-value reference. from this information we can: select one: a. accept the null hypothesis because the p-value obtained shows that the difference between the two groups being tested is not statistically significant b. accept the null hypothesis because the p-value obtained was statistically significant c. reject the null hypothesis because of the p-value obtained d. reject the null hypothesis because the data obtained is statistically significant
