Question

If the confidence level is 90% what is the value of

Answer 1

The value of a which is the level of significance would be = 0.10

How to calculate the level of significance of a given data?

To calculate the level of significance of a given data, the following steps should be taken as follows:

The sample size (n) = 2000

The sample proportion (p) = 13%

= 13/100 = 0.13

q = 1- p = 1-0.13 = 0.87

Confidence interval = 90%= 0.90

Level of significance (a) = 1-0.90

= 0.10

Answer 2

Given

n = 2000

p = 13% = 0.13

margin of error = 4% = 0.04

Find

If the confidence level is 90% what is the value of a.

Step-by-step explanation

From the given information ,

p = 0.13

q = 1 - 0.13 = 0.87

margin of error = 0.04

confidence level = 90% = 0.90

`\begin{gathered} \alpha=1-0.90 \\ \alpha=0.10 \end{gathered}`

Final Answer

Hence , the value is 0.10
