Which answer is an example of an experimental study?
A researcher asks all the students in a classroom to answer questions about whether they would attempt a difficult math problem if they were promised a candy bar for correctly solving it. The researcher keeps track of students' answers.
A researcher attends a math class and watches and records how many students attempt the difficult problems assigned in class.
A researcher asks two groups of students to solve a difficult math problem. One of the groups is told that members will receive a candy bar after correctly solving the problem. The other group is not told this. The researcher keeps track of how long people attempt to solve the math problem.
A researcher asks a sample of the students in a classroom to answer questions about how long they would attempt to solve a difficult math problem if they were promised a candy bar for correctly solving it. The researcher keeps track of students' answers.

- Use the RAND function and the Copy command to generate 100 random numbers. a. What fraction of the random numbers are smaller than 0.5? b. What fraction of the time is a random number less than 0.5 followed by a random number greater than 0.5? c. What fraction of the random numbers are larger than 0.8? d. Freeze these random numbers. However, instead of pasting them over the original random numbers, paste them onto a new range. Then press the F9 recalculate key. The original random numbers should change, but the pasted copy should remain the same.arrow_forwardThe file P02_41.xlsx contains the cumulative number of bits (in trillions) of DRAM (a type of computer memory) produced and the price per bit (in thousandth of a cent). a. Fit a power curve that can be used to show how price per bit drops with increased production. This relationship is known as the learning curve. b. Suppose the cumulative number of bits doubles. Create a prediction for the price per bit. Does the change in the price per bit depend on the current price?arrow_forwardThe game of Chuck-a-Luck is played as follows: You pick a number between 1 and 6 and toss three dice.

In our case that is 1/20% = 5 years = customer lifetime. A supermarket chain ran a social media campaign and they got 2,000 new customers. The TOTAL cost of the campaign was $250,000. These customers visited the supermarket 25 times a year. Each customer spends $100 per visit and the supermarket makes a 4% profit margin on the customer’s spend. The retention rate of the customers is 60%. What is their CLV? Assume that the profit margin is based on the customer’s non-discounted spend, then deduct the discount.arrow_forward

- The Commission of Education reported that 47% of college freshmen earn a degree and graduate within 5 years. Assume that the graduation records show that women make up 50% of the students who graduated within 5 years, but only 45% of the students who did not graduate within 5 years. The students who had not graduated within 5 years either dropped out or were still working on their degrees. a. Let A1 = the student graduated within 5 yearsA2 = the student did not graduate within 5 yearsW = the student is a female student Using the given information, what are the values for P(A1), P(A2), P(W ǀ A1)and P(W ǀ A2)?

You will need to develop a table to calculate the slope and the intercept. Use that formula to forecast television sales for years 11 and 12.arrow_forwardFunctions are used to map elements from one set to another. For example, barcode and QR scanner systems are developed by programmers to use specific symbologies to map the pattern in the barcode to actual digits. The check digit or the final digit is used to determine whether the function is true (known good) or false (errors in the mapping occurred). RFID system developers also use functions to develop a pairing protocol that securely connects legitimate devices within a specific proximity. RFIDs are using in logistics, retail, warehousing, and more.arrow_forward
