- In a previous Paul, 44% of adults and children under the age of 18 reported that their family eat dinner together seven nights a week... use technology to find the P value. P value =_. (round to three decimal places as needed.) should one reject the null hypothesis? or should one not reject the null hypothesis?We ask a random sample of 1000 New Zealanders their opinion on whether New Zealand should become a republic with a president replacing the Queen as head of state and 350 answer ‘yes’. We are testing the following pair of hypotheses for the value of p, the true proportion of New Zealanders who think that New Zealand should become a republic with a president replacing the Queen as head of state: H0: p = 0.40 Ha: p > 0.40 Select the correct value (to 3 decimal places) of the z-test statistic for this sample from the list below.

- Data from the 2014 General Social Survey (GSS) show that out of n=1,606 adult respondents, the proportion who reported having voted for Barack Obama in the 2008 presidential election was 0.61 Q: If I calculate a z test static of 4.84, and my alpha = 0.05, what decision should I make about the hypothesis? (Calculate the p-value for a 2-sided test to make your decision.) Options: A: fail to reject the null hypothesis that the proportion of American adults who voted for Obama in 2008 was 0.55 B: reject the null hypothesis that the proportion of American adults who voted for Obama in 2008 was 0.55 C: Reject the alternative hypothesis that the proportion of American Adults who voted for Obama in 2008 was not equal to 0.55 D: Fail to reject the alternative hypothesis that the proportion of American adults who voted for Obama in 2008 was not equal to 0.55A random sample of 50 students was asked to estimate how much money they spent on textbooks in a year. The sample skewness of these amounts was found to be 0.83 and the sample kurtosis was 3.98. Test at the 10% level the null hypothesis that the population dis- tribution of amounts spent is normal.Suppose researchers draw a sample of 300 breakfast sandwiches from a certain fast-food restaurant, and carry out a t test of the null hypothesis that the true mean sodium content is 1000, against the alternative hypothesis that it is greater than 1000. They find a negative value of the test statistic, and a p-value of 0.85. What would the p-value have been had they used a two-sided alternative hypothesis? (Give your response to at least 3 decimal places. Give only your numeric response, and not any extra characters or symbols.)
