A teacher was listening to some of her students talk about how many SnapChats they send during the day. The teacher decided that she wanted to conduct a study to see if the number of SnapChats a student sends per day affects how much time students talk to their friends face-to-face. So, the teacher let her 2nd period class continue sending Snaps as they always have. Then, the teacher told her 5th period that they were to not watch use SnapChat for a whole day. Then, the teacher had students record how many conversations they had with their friends during the week, gathered the data, and analyzed the results. What type of study is this? Experimental or observational?

A third-grade teacher is interested in comparing the effectiveness of two styles of instruction in language comprehension: imagery, in which the students are asked to picture a situation involving the word, and repetition, in which the students repeat the definition of the word multiple times. After 6 weeks of instruction, she gives the students a language comprehension test. The following scores are the number of correct answers for each student. Determine whether the two styles of instruction differ in their effectiveness. Imagery: 12, 13, 11, 11, 13, 13, 15, 12, 9, 12 Repetition: 6, 11, 10, 12, 9, 10, 11, 12, 10, 8 Answer the quetions in picture provided using above information. Thank you
The past records of a supermarket show that its customers spend an average of $110 per visit at this store. Recently the management of the store initiated a promotional campaign according to which each customer receives points based on the total money spent at the store, and these points can be used to buy products at the store. The management expects that as a result of this campaign, the customers should be encouraged to spend more money at the store. To check whether this is true, the manager of the store took a sample of 14 customers who visited the store. The following data give the money (in dollars) spent by these customers at this supermarket during their visits. 106.13 107.43 124.68 124.88 101.17 72.75 85.45 86.05 100.4 98.84 101.63 95.56 89.40 119.52 Assume that the money spent by all customers at this supermarket has a normal distribution. Using a 2.5% significance level, can you conclude that the mean amount of money spent by all customers at this supermarket after the…
In a section of an English 201 class, the professor decides to be "generous" with the students and will grade the exam in a unique way. Grades will be assigned according to the follwing rule: the top receives A's, the next 20% receive B's, the middle 40% receive C's, the next 20% receive D's, and the bottom 10% receive F's. Some may refer to this as "curving" The 40 grades were as follows: 30, 53, 88, 69, 77, 57, 58, 43, 63, 51, 69, 88, 86, 84, 50, 83, 91, 76, 57, 90, 45, 79, 41, 80, 62, 66, 71, 58, 92, 85, 57, 74, 63, 60, 99, 85, 70, 93, 67, 53 Do you think ths method of grading is fair to all students? Explain your answer 2. Under what circumstances would some students NOT like this method of grading? 3. Find the lowest score on the final exam that would qualify a student for an A, a B, a C, and a D 4. After doing the previous 3 parts explain the term "grading on a curve" what does it involve? what curve is it referring to?
