Expert Answer
It is given that in the survey, it is found that 109 out of 341 video gamers said that they prefer playing games on a console rather than a computer or hand held device. Let p be the sample proportion
1.
The null and alternative hypotheses are given below.

Н. : Р-0.30 Ha P 0.30
Since the alternative hypothesis have not equal sign, the test is two-tailed test.
2.
The critical value for 0.10 level of significance can be obtained by entering the formula “=NORM.INV(0.95,0,1)” in EXCEL software.
