Answer:
<u>The proportion of women who ran the marathon and had a finishing time less than Kathy's is 66% (rounding to the next whole)</u>
Explanation:
1. Let's review the information given to us to answer the question properly:
μ of finishing time for women = 259 minutes
σ of finishing time for women = 32 minutes
Finishing time for Kathy = 272 minutes
2. What proportion of women who ran the marathon had a finishing time less than Kathy's? Show your work.
Let's calculate the z-score for the finishing time for Kathy, as follows:
z-score = (272 - 259)/32
z-score = 13/32 = 0.41 (rounding to the next hundredth)
Using the z-table, now we can calculate the proportion of women who ran the marathon had a finishing time less than Kathy's:
p (z=0.41) = 0.6591
<u>The proportion of women who ran the marathon and had a finishing time less than Kathy's is 66% (rounding to the next whole)</u>
Answer:
B. The new technologies would reduce positive checks on population.
Explanation:
Since there would be better and more efficient methods of farming that would reduce the positive checks that happen to the population. The positive checks would at first be a lot less impactful than before the technology. Disease and natural disasters would not cripple a population until it grows to a much larger number.
Answer:
Metacognition
Method of loci
Deep processing
Rehearsal
Elaboration
Chunking
Mental set
Explanation:
1.) Metacognition refers to one's awareness of and ability to regulate one's own thinking. David had this awareness that he has difficulty remembering what he had studied. He was reminding himself that he should try to remember all battles he had studied.
2.) The method of loci David employed, is a strategy of memory enhancement in which at first, he began by just trying to group all of the facts associated with each battle into his memory in order to enhance the recall of information. On David memory journey, or palace, he tried three different mind palace technique.
3.) David Deep processing enabled him to start repeatedly associating the events that occurred in each battle with the place where the battle occurred which created a much stronger memory trace.
4.) David personally drill himself by rehearsing what he had read in preparation for the examination
5.) David initial method of loci was unable to elaborate the details of wars. And lack the process of developing or presenting a system for further detail.
6.) Chunking refers to an approach David took for making more efficient use of short-term memory by asking his friend for better method of loci. David new Chunking was to making up stories about each battle and how each battle is connected with other battles into units or chunks. The resulting chunks are easier to commit to memory than rehearsing a longer one.
7.) David will surely create a new Mental set toward his studies. When he tried his friend method and found it to be much more effective.
He will have a tendency to approach any other subjects the same way because that way worked in the past
