Suppose we want a 90% confidence interval for the average amount of time (in minutes) spent per week on homework by the students
ki77a [65]

Answer: 482

Step-by-step explanation:

Formula to find the sample size is given by :-

n= (\dfrac{z^*\times \sigma}{E})^2                                    (1)

, where z* = critical z-value (two tailed).  

\sigma = Population standard deviation and E = Margin of error.

As per given , we have

Margin of error : E= 3

\sigma=40

Confidence level = 90%

Significance level =\alpha=1-0.90=0.10

Using z-table , the critical value for 90% confidence=z^*=z_{\alpha/2}=z_{0.05}=1.645

Required minimum sample size = n= (\dfrac{(1.645)\times (40)}{3})^2   [Substitute the values in formula (1)]

n=(21.9333333333)^2

n=481.07111111\approx482  [ Round to the next integer]

Hence, the number of observations required is closest to 482.
