Answer:
False
Step-by-step explanation:
A number that can expressed as ,
Where, p and q are integers such that q ≠ 0, is called a rational number.
Also, a decimal number with repeating pattern is a rational number,
( for eg : 0.333.... = )
Since,
√3 = 1.73205080757.....
∴ There is no repeating pattern
Thus, √3 is not a rational number.
Given statement is FALSE.
Answer: a. n= 1068
b. n= 164
Step-by-step explanation:
The formula to find the sample size :
, where p=prior population proportion , z* = critical z-value and E = Margin of error.
Here , let p=proportion of computers that use a new operating system.
Given : Confidence level = 95%
i.e. z* = 1.96 [by z-table]
Margin of error : E = 3% =0.03
a. If p is unknown , then we assume p=0.5
Then,
i.e. n= 1068
b. p=0.96
Then,
i.e. n= 164.
