Weinstein, mcdermott, and roediger (2010) report that students who were given questions to be answered while studying new material had better scores when tested on the material compared to students who were simply given an opportunity to reread the material. in a similar study, an instructor in a large psychology class gave one group of students questions to be answered while studying for the final exam. the overall average for the exam was μ = 73.4 but the n = 16 students who answered questions had a mean of m = 78.3 with a standard deviation of σ = 8.4. for this study, did answering questions while studying produce significantly higher exam scores? use a onetailed test with α = .01. gravetter, frederick j. statistics for the behavioral sciences (p. 296). cengage learning. kindle edition.

is this part of a question or something

if farmer matt works for 8 hours a day, how many days will it take him to completely plant 12 rows of crops? each batch of cookies needs 3/4 cups of sugar.

step-by-step explanation:

the above table 1 will calculate the population size (n) after a certain length of time (t). all you need to do is plug in the initial population number (no), the growth rate (r) and the length of time (t). the constant (e) is already entered into the equation. it stands for the base of the natural logarithms (approximately 2.71828). growth rate (r) and time (t) must be expressed in the same unit of time, such as years, days, hours or minutes. for humans, population growth rate is based on one year. if a population of people grew from 1000 to 1040 in one year, then the percent increase or annual growth rate is 40/1000 x 100 = 4 percent.
