The following is the pattern of agreement with the financial assistance policy obtained from a group of 30 residents under the Covid-19 pandemic. 44 50 10 36 39 Agreement Categories 25 35 2 3 5 6 N 30 2. A survey of 46 people shows that 35 agree with the current housing policy and 15 disagree. 32 Can you reject at Of = .05 the following null hypotheses? Observed Frequency 15 2 3 4 30 13 39 41 14 28 32 Ho: the problem is drawn from a population in which p=q=1/2. (a) At =0.05, can we say that the proportions in all of the agreement categories are the 15 35 33 same? Show your work. (b) Is there other suitable test for the same problem? If yes, why? If no, why? At a=0.01, can you conclude that the population proportion of increase in fish production is the same as the population proportion of decrease in fish production? The following is the opinion poll of the support of an issue by two groups of people: oppose favour 6. A survey of 46 primary school principals shows that 28 agreed with the suspension of classes due to the threat of coronavirus and 12 disagreed. Should we reject at CC = 0.05 group X he following null hypotheses? group Y Ho: The sample was drawn from a population in which the proportion of disagreement p = 0.2. Can you conclude at 0 = .05 that the population proportions of groups x and y supporting the
