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

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

= $3.42 \ \pm \ 1.96\times 0.073$

= $3.42 \ \pm \ 0.143$

= $3.29, 3.57$
