- 7.6 ; - 7.399 ; - 7.0699 ; - 7.06; - 1.639; - 0.6299.

A little tip to help you with negatives: The bigger the number is, the less value it has. If you still have struggles with it, try drawing a number line for a visual. The farther away a negative number is from 0, the less value it has.

assume the age of night school students is normally distributed. A simple random sample of 24 night school students had an avera
aleksley [76]
Let
n = number of data
s = standard deviation (sample)
S = standard deviation (population)

The working equations is

\frac{(n-1) s^{2} }{ x^{2}_{right} }  \ \textless \   S^{2} \ \textless \   \frac{(n-1) s^{2} }{ x^{2}_{left} }

To find x^{2}_{right}, : (1 - 0.90)/2 = 0.05

To find x^{2}_{left}, : 1 - 0.05 = 0.95

Degrees of freedom = n-1 = 24 - 1 = 23

This is shown in the figure attached. Since there is no row for df=23, we interpolate. Thus,

 x^{2}_{left} = 13.093 

 x^{2}_{right} = 35.17 


Substitute all values,

\frac{(24-1) 5.6^{2} }{ 35.17} \ \textless \ S^{2} \ \textless \ \frac{(24-1)  5.6^{2} }{ 13.093} }

Thus the answer is,

20.51\  \textless \ S^{2} \ \textless \ 55.09

Hello, please help! I will be using this a lot within the next few days lol
lina2011 [118]

Answer:

1/2

Step-by-step explanation:

1/3 + 1/6

LCM of 3 and 6 is 6.

therefore, multiple the fraction that doesn't have 6 as denominator with a fraction that makes the denominator equal to the LCM.

1/3 × 2/2 = 2/6

(we have used 2/2 because 3×2= 6)

so,

2/6+1/6 = 2+1/6

(2 + 1 whole divided by 6)

therefore we get,

3/6

on simplification,

3/6 = 1/2 = 0.5

hope it helps!!
