Short Answer
!!!DO NOT ENTER WHAT I PUT! THESE ARE FOOTNOTES FOR YOU TO PUT IN YOUR OWN WORDS!!!
a: you don't know the opinion of the students
b: it is biased, negative adjectives
c: about 94.5
I'm so confused with this lesson. I just did the work for question 3 on Connexus 5.6.6 (Estimating Population Size Quiz) and I got 6,600. that's not an answer.
Here's my work:
A fish and game warden captures and tags 66 deer and releases them. A month later, he captures 100 deer and finds that 17 of them have tags.
Total number of tagged deer in sample/total number of deer in sample = 17/100
Total number of tagged deer in population/total number of deer in population = 66/x
17/100 = 66/x
17x = 100*66=6600
I guess you could divide 17 into 6600. That would give you 388.235294, which if rounded to the nearest whole number is 389.
uhh theres 6 multiple choice, not 3

@same bro lol is correct
steps for number 5? im confused
BROTHER!
am i anonymus
lmaoooo billy bob reminds me of fifth grade
This web sight is VEEEEEEEERRRY HELPFULL😁😁😁😁😁😁😁😁😁😁
@Help is here is wrong on the short answer questions, answer the questions on your own, if you are having trouble here I'm going to start it off and give you opinion why-
For A. on question 7 "They had a fair chance because" - put in your own words and add on.
For B. "It is biased because" - add on why you think it is biased, if you think the opposite write that but don't because its wrong.
C. Give the percentage of people who said "NO" not "YES" only "NO"
The percentage is 3% add some words to it, so you dont get told you cheated or got help. :)

#4. Lucy wants to find out the number of frogs in a pond near her house. She catches 54 of them, puts a leg band on each frog, and puts them back in the pond. The next week, she catches 70 frogs. Of the 70 frogs, 13 have a leg band. Based on this information, what is a reasonable estimate of the number of frogs in the pond?
A) 208 B) 632 C) 291 D) 111
70 frogs/13 with a leg band*54 that she originally caught=290.769 estimated in the pond 70/13*54=290.769
Yes
@Same Bro lol is right, also there is 3 questions ig it's just updated
Also @help is here is right for the 1-6 questions if you want answers to number 7 look above at my first comment!
DCB is correct for 2022

THE JAEGER BROTHERS-
@Help is here is correct from 1-6
connexus june 2022
In a sample of 50 museum visitors one afternoon, 22 were female and 28 were male. If there were 800 museum visitors that afternoon, estimate the number of visitors who were female.
A. 220
B. 352
C. 448
D. 700
To estimate the number of visitors who were female, we can use the formula:
Number of females in sample / Total number of people in sample = Number of females at event / Total number of people at event
Substituting the given values, we get:
22 / 50 = x / 800
Cross-multiplying, we get:
50x = 22 * 800
Simplifying, we get:
x = (22 * 800) / 50
x = 352
Therefore, an estimate of the number of visitors who were female is 352.
Hence, the answer is (B) 352.
For 5, there were 22 females, so you can divide that by 50 (the total number of people), and then multiply the answer you just got by 800, and you will get your final answer.
For 6 do the same as for 5, divide 4/100,and then multiply the number you got by 750, to get your answer.
If you are in connections acadademy, you should be embrassed. In Unit 5 Lesson 6 it went over on how to do this, there is a formula and it very very easy to understand.
Number of X (e.g. woman) in sample Number of X (woman) at event
=
Number of X (e.g. people) in sample Number of X (people) at event
You then cross multiple and more than likely there is a X on one of them so for example this is how to solve question 5:
In a sample of 50 museum visitors one afternoon, 22 were femael and 29 were male. If there were 800 museum visitors that afternoon, estimate the number of visitors who were female.
22 x
=
50 800
50 ⋅ x = 50x
22 ⋅ 500 = 17,600
50x = 17,600 (We are trying to find the X and the first step is to get it by itself, right now its multiplying with the "50" so divided 50 by 50 and get zero. Now what you do on one side you have to do on the other, so 17,600 divided by 50 = 352)
17,600 divided by 50 = 352
3 is right
4 which one do you think it is?
5 is wrong
6 which one do you think it is?
