Answer:

The required interval is (26.23 , 27.37)

Step-by-step explanation:

The mean is = 26.8

The standard deviation is = 7.42

n = 654

At 95% confidence interval, the z score is 1.96

To find the desired interval we will calculate as:

$26.8+1.96(\frac{7.42}{\sqrt{654} } )$

And $26.8-1.96(\frac{7.42}{\sqrt{654} } )$

$26.8+0.57$ and $26.8-0.57$

= 27.37 and 26.23

So, the required interval is (26.23 , 27.37)

IceJOKER [234]

$\frac{1}{2}$ and $\frac{1}{3}$

There are 6 possible outcomes when rolling a die, 1, 2, 3, 4 , 5, 6

numbers less than 4 are 1, 2, 3

P( number less than 4 ) = $\frac{3}{6}$ = $\frac{1}{2}$

numbers greater than 4 are 5, 6

P( number greater than 4 ) = $\frac{2}{6}$ = $\frac{1}{3}$
