Katrina wants to estimate the proportion of adults who read at least 10 books last year. to do​ so, she obtains a simple random
Vaselesa [24]
E=Z*sqrt (p(1-p)/N), where E= error margin, p=proportion, N=sample size

Katrina's margin error at 85% confidence interval: E=1.96*sqrt (p(1-p)/100) = 0.196 sqrt (1(1-p))

Mathew's margin error at 99% confidence interval: E= 2.58*sqrt (p(1-p)/400) = 0.129 sqrt (p(1-p))

Since both obtained same estimate of proportion (that is, value of p), it can be seen that Mathew's estimate will have a small error (That is, 0.129 is smaller than 0.196). This can be attributed to larger sample size although a wider confidence (99%) interval was considered.

Umnica [9.8K]

Formula to convert F to C:

(F -32) x 5/9

F = 63 + 10 = 73

73-32 = 41

41 x 5/9 = 22.77777

Rounded to the nearest degree = 23 C

Which of the following situations would best be modeled by a discrete relationship? a. A teacher counts the number of students i
Nata [24]

Answer:

Option d is correct.

Step-by-step explanation:

Discrete values are those which take an integer value not in fraction.

Option A is discrete because there will be certain number of students in class say 20 or 30

We can not have 20.5 students

Therefore, option a is correct.

Option B is not discrete because many people can have age say 65 and a half years and weight can be in decimals say 50.5 kgs.

Option C is correct because he is saving a proper integer number of money.

Therefore, option d is correct that is both A and C are correct.
