A building contractor has a chance to buy an odd lot of 1,000 used bricks at an auction. She is interested in determining the proportion of bricks in the lot that are cracked and therefore unusable for her current project, but she does not have enough tir inspect all 1,000 bricks. Instead, she checks 150 bricks to determine which ones are cracked. What is the population of interest? all building contractors all 1,000 bricks in the lot the rest of the 850 bricks the 150 bricks selected for inspection the rest of the 700 bricks What group constitutes the sample? the 150 bricks selected for inspection all building cor ctors the rest of the 700 bricks all 1,000 bricks in the lot the rest of the 850 bricks

A professor wanted to study the number of hours statistics students spend studyingstatistics each week. Out of 19 statistics sections at Santa Ana College, the professorsurveyed each student from 3 randomly selected sections. What is the largest group ofstudents the results of this study can represent?a. All Santa Ana College studentsb. All Santa Ana College students taking a math classc. All Santa Ana College students taking a statistics classd. Students in the three sections the professor surveyed

You roll a six-sided die 60 times and got the following tally: 20 ones, 20 twos, 15 threes, 3 fours, 2 fives, 0 sixes Does this seem like a reasonable result? What inference might you draw from this result?

A large group of people get together. Each one rolls a die 120 times, and counts the number of aces (with a single dot). About what percentage of these people should get counts in the range 10 to 30? Choose the closest answer.

Suppose you are asked to toss a coin 16 times and calculate the proportion of the tosses that were heads?

If a coin is flipped 225 times and the number of Hs is 75. Compute the proportion of Hs. Round to three places.

In a class of 20 there are 4 who participate in band. What percent of the class participates in band? % of the class participates in band. (Type an integer or a decimal.)

in a survey of 14 college students, it was found that 9 were taking an English class, 7 were taking a math class, and 6 were taking both English and math. How many students were taking a math class only? How many students were taking an English class only? How many students were taking neither.

We are interested in estimating the proportion of people that can identify Nebraska but not Vermont. In a class of 55 students, each student was requested to select a sample of 6 people, show each person a map of the US and ask the person to identify the states of Vermont and Nebraska. The following numbers are the counts that each student got, that is, each number is the count of people in the student sample of 6, that could identify Nebraska but not Vermont.3344010110020030002020001100002010000001000200000001010Note: You can cut and past these numbers into an excel spreadsheet to help you calculate the mean and the standard deviation and compute the confidence interval. If you have trouble pasting them, paste them to a text file first and then copy from there.When we collect all the students' data, we have a sample size of 6x55=330.Of the sample of 330 people, what proportion were able to locate Nebraska but not Vermont? (round answer to 3 decimals) Find a 95% confidence interval for…
