Response Question
Paha777 [63]

Answer:

The right solution is "3.29, 3.57".

Step-by-step explanation:

Seems that the given problem is incomplete. Below is the attachment of the complete and appropriate query.

<u>The given values are</u>:

Randomly selected adults,

n = 105

Mean,

\bar{x} = 3.42

Standard deviation,

s = 0.75

Now,

At 95% confidence level if given by,

=  \bar{x} \ \pm \ Z_{\frac{\alpha}{2} }\times \frac{s}{\sqrt{n} }

On putting the given values, we get

=  3.42 \ \pm \ Z_{\frac{0.05}{2} }\times \frac{0.75}{\sqrt{105} }

=  3.42 \ \pm \ 1.96\times 0.073

=  3.42 \ \pm \ 0.143

=  3.29, 3.57
