There are 65 people in the club.

Step-by-step explanation:

Given,

Fraction of people went on hiking = $\frac{3}{5}$

No. of people went on hiking = 39

Let,

x be the number of people at club.

According to given statement;

$\frac{3}{5}\ of\ x = 39\\\\\frac{3}{5}x=39\\0.6x=39\\$

Dividing both sides by 0.6

$\frac{0.6x}{0.6}=\frac{39}{0.6}\\x=65$

There are 65 people in the club.

confidence interval for the mean battery life in the new model is [7.9489, 8.3045].

What is confidence interval ?

A confidence interval, in statistics, refers to the chance that a population parameter can fall between a collection of values for an exact proportion of times.

Main body:

Formula for confidence interval is =

CI = x- bar ± z*s/√n where,

CI = confidence interval

x- bar = sample mean

z = confidence level value

{s} = sample standard deviation

{n} = sample size

given ;

n = 6

mean = (8.23+7.89+8.14+8.25+8.30+ 7.95)/6

= 8.127

value of z for 95% C.I. = 1.96

C.I. = 8.127 ± 1.96 * 0.22/√6

C.I. = 8.127 ± 0.1781

C.I. =[7.9490, 8.3044]

Hence correct option is A.
