- This is the full questionarrow_forwardSelect the appropriate null and alternative hypothesis for the following research question: Do people who live in a urban areas prefer to stream their tv/movies the same as people who live in rural areas? phat1 = proportion of people who live in urban areas that prefer to stream tv/movies phat2 = proportion of people who live in rural areas that prefer to stream tv/movies A. Null Hypothesis: People who live in urban areas prefer to stream their tv/movies less than or equal to people who live in rural areas i.e. phat1 <= phat2 Alternative Hypothesis: People who live in urban areas prefer to stream their tv/movies more than people who live in rural areas i.e. phat1 > phat2 B. Null Hypothesis: People who live in urban areas prefer to stream their tv/movies more than or equal to people who live in rural areas i.e. phat1 >= phat2 Alternative Hypothesis: People who live in urban areas prefer to stream their tv/movies less than people who live in rural areas i.e. phat1 <…arrow_forwardTest the claim that the proportion of people who own cats is significantly different than 10% at the 0.05 significance level.The null and alternative hypothesis would be: H0:p≥0.1�0:�≥0.1H1:p<0.1�1:�<0.1 H0:p=0.1�0:�=0.1H1:p≠0.1�1:�≠0.1 H0:μ≥0.1�0:�≥0.1H1:μ<0.1�1:�<0.1 H0:μ≤0.1�0:�≤0.1H1:μ>0.1�1:�>0.1 H0:p≤0.1�0:�≤0.1H1:p>0.1�1:�>0.1 H0:μ=0.1�0:�=0.1H1:μ≠0.1�1:�≠0.1 The test is: left-tailed right-tailed two-tailed Based on a sample of 200 people, 18% owned catsThe p-value is: (to 2 decimals)Based on this we: Fail to reject the null hypothesis Reject the null hypothesisarrow_forward

A researcher believes that the proportion of children taking the new antibiotic who experience a headache as a side effect is more than 0.02. We know that the null hypothesis is H0 : p = 0.02 and the alternative hypothesis is H1 : p > 0.02. Suppose that the sample evidence indicates thata. the null hypothesis is rejected. State the conclusion.b. the null hypothesis is not rejected.
