Answer:
<h3>The given statement " The distribution of the sample mean, x-bar, will be normally distributed if the sample is obtained from a population that is normally distributed, regardless of the sample size " is <u>
True. </u></h3>
Step-by-step explanation:
Given statement is " The distribution of the sample mean, x overbar, will be normally distributed if the sample is obtained from a population that is normally distributed, regardless of the sample size".
<h3>To check whether the given statement is true or not :</h3>
- The distribution of the sample mean, x-bar, will be normally distributed if the sample is obtained from a population that is normally distributed, regardless of the sample size is <u>True. </u>
- The standard error of the mean is divided into half, then the sample size must be doubled.
∴ The given statement is true.
Answer:
The first option is correct, 12/30 and 25/30
Step-by-step explanation:
To get common denominators, you need to find the GFC (greatest common factor) of 5 and 6, which is 30. Then you would need to make the fractions equal the same as the original fractions, by multiplying.
2/5 = ?/30 <- you can see that 30 is 6 times more than 5. so this means you multiply 2 by 6 to get 12. 12/30
5/6 = ?/30 <- you can see that 30 is 5 times more than 6. so this means you multiply 5 by 5 to get 25. 25/30
Answer:
Correct option is
B
1.x+0.y=7
x=7 can be written as, 1.x+0.y=7 as the coefficient of x is 1 and that of y is 0. Step-by-step explanation:
Answer:
V=925 because 18.5x12.5x4=925

Answer:
Option D (APEX)
Step-by-step explanation:
L= Student has lice
NL= Student has no lice
PT=Test Shows positive
NT=Test Shows negative
P(
) =0.7708 (Probability that a student has no lice and the test shows negative)
P(
) = 0.0108 ( Probability that a student has lice and the test shows negative)
= ![\frac{P\frac{NT}{NL} }{P\frac{NT}{NL} +P\frac{NT}{L} }](https://tex.z-dn.net/?f=%5Cfrac%7BP%5Cfrac%7BNT%7D%7BNL%7D%20%7D%7BP%5Cfrac%7BNT%7D%7BNL%7D%20%2BP%5Cfrac%7BNT%7D%7BL%7D%20%7D)
![\frac{0.7708}{0.7708+00108}](https://tex.z-dn.net/?f=%5Cfrac%7B0.7708%7D%7B0.7708%2B00108%7D)
![\frac{0.7708}{0.7816}](https://tex.z-dn.net/?f=%5Cfrac%7B0.7708%7D%7B0.7816%7D)
- 0.98618219 (Simplify)
<u> Terms Of Percentages</u>
0.98618219 × 100
=98.6
Therefore your answer is 98.6% (Option D)
