In a memory​ experiment, Alice is able to memorize words at a rate given by M′(t)=−0.003t2+0.6t. In the same memory​ experiment, Ben is able to memorize words at the rate given by M′(t)= −0.015t2+0.6t.

a) who has the higher rate of memorization?

​b) How many more words does that person memorize from t=0 to t=0 (during the first 10 minutes of the experiment)

c) Over the first 10 minutes of the​ experiment, on​ average, how many words per minute did Alice​ memorize?

d) Over the first 10 minutes of the​ experiment, on​ average, how many words per minute did Ben​ memorize?

A cognitive psychologist believes that a particular drug improves short-term memory. The drug is safe, with no side effects. An experiment is conducted in which 8 randomly selected subjects are given the drug and then given a short time to memorize a list of 10 words. The subjects are then tested for retention 15 minutes after the memorization period. The number of words correctly recalled by each subject is as follows: 9, 10, 12, 7, 10, 8, 7, 9. Over...

12. In a study of memory recall, 5 people were given 10 minutes to memorize a list of 20 words. Each was asked to list as many of the words as he or she could remember both 1 hour and 24 hours later. The result is shown in the following table. Assume we want to use a 0.05 significance level in your analysis. The research question is: Do students recall significantly more words after 1 hour than after 24 hours...

A study is done to determine whether regular exercise improves short term episodic memory. Researchers randomly select a group of 10 people that do not get regular exercise and give them 1 minute to memorize a list of 40 words. After this, they record how many words each person was able to recall. Then, they have everyone in the sample complete an hour of vigorous exercise every day. After eight weeks they again give each person 1 minute to memorize...

An institute finds that the average student taking Elementary Shorthand will progress at a rate given by dQ/dt = k(70 − Q) in a 20-wk course, where Q(t) measures the number of words of dictation a student can take per minute after t wk in the course. If the average student can take 50 words of dictation per minute after 10 wk in the course, how many words per minute can the average student take after completing the course? (Round...

For time 0<t<10 water is flowing into a small tub at a rate given by the function F defined by F(t) = arctan(pi/2-t/10). For time 5<t<10 water is leaking from the tub at a rate given by the function L defined by L(t) = 0.03(20t -t^2-75). Both F(t) and L(t) are measured in cubic feet per minute, and t is meaured in minutes. The volume of water in the tub, at time t is given by W(t). a. At t...
