Answer:

0.269,0.629

Step-by-step explanation:

Ivan surveyed randomly selected 49 players out of 134.

22 of the players said that they preferred that the games be played on Saturdays.

Here,

p = proportion = \dfrac{22}{49},

n = sample size = 49,

We know that,

\text{M.E}=Z_{critical}\cdot \sqrt{\dfrac{p(1-p)}{n}}

It is given as 18% or 0.18

We also know that, confidence interval will be

=p\pm \text{M.E}

Putting the values,

=\dfrac{22}{49}\pm 0.18

=0.449\pm 0.18

=0.269,0.629
