Answer 1

Given that, In clinical trials, 213 of 224 patients suffering from acid refilx disease were healed after 8 weeks.

level of significance $(\alpha)$ = 0.01

The null and the alternative hypotheses are,

H₀ : p = 0.94

H_a : p > 0.94

Using TI-84 calculator we get,

Test statistic is, Z = 0.69

p-value = 0.246

Here, p-value = 0.246 > $\alpha = 0.01$

So, we fai to reject the null hypothesis ( H₀).

Therefore, with a P-value of 0.246 we fail to reject the null hypothesis.

The given data does not provide significant evidence that the proportion of Nexium users who heal within 8 weeks is more than 0.94
