An educational report asserts that 70% of all young adults start planning their career at the age of 18. In a sample of 1000 adults, 744 started their career plans at the age of 18. Test whether the true proportion of all young adults who began planning their career at the age of 18 is more than 70% at the 5% significance level. What is the decision regarding the null hypothesis at the 5% significance level, using the critical value approach?Group of answer choices The decision is to rejectH 0 because the test statistic falls in the rejection region [1.645, ∞). The decision is to rejectH 0 because the test statistic falls in the rejection region [1.960, ∞). The decision is to rejectH 0 because the test statistic falls in the rejection region (-∞,-1.645]. The decision is not to rejectH 0 because the test statistic does not fall in the rejection region (-∞,-1.645] U [1.645, ∞). The decision is not to rejectH 0 because the test statistic does not fall in the rejection region (-∞,-1.960] U [1.960, ∞).
