1. Millennials really enjoyed attending concerts especially Korean artists, 75% of the millennial preferred watching Korean concert over local. During lockdown, out of 150 randomly chosen for a survey (through online), 105 said they still watch Korean artist concert after the pandemic. Does this indicate that some millennial are losing interest in watching Korean artist concert? Use 0.05 level of significance.

Step 3.

07. 0 =

414 . 1 − =

Step 4. The alternative hypothesis is

tailed test-directional. Hence, the one

shall be used.

05 . 0 =

0.05 = 0.45 – 0.5

Using the Areas Under the Normal

= 1.645. Hence, at the 5% Curve Table,

level of significance, the critical value

1.645. – is

Step 5. Since the computed test statistic

1.414 does not fall in the rejection – =

region, do not reject the null

hypothesis. Conclude that at 0.05 level

e is not enough of significance, ther

some evidence to conclude that
