Cameroon Adult Literacy Rate ~ The adult literacy rate in the sub-Saharan country of Cameroon is the percentage of the adult population who can, with understanding, read and write short, simple statement on their everyday life. Generally, "literacy" also encompasses "numeracy", the ability to make simple arithmetic calculations.The adult literacy rate in Cameroon was reported as 77.22% in 2018, according to the World Bank collection of development indicators, which is compiled from officially recognized sources. Science educators are interested in finding out whether the adult literacy rate in Cameroon has changed since 2018. They randomly sample 225 adults in Cameroon and find that 184 meet the standard of "literate," based on simple literacy and numeracy tests.1. The science educators want to conduct a hypothesis test for their research question. Which test is most appropriate for this scenario?A. One sample Z-test for a population proportion B. 22 goodness of fit test C. 22 test of independence D. One sample t-test for a population mean

2. Which of the following conditions must be met for the hypothesis test to be valid? Check all that apply. A. np010np010 and n(1p0)10n(1p0)10 B. The null standard error must be at least 5. C. The sample size must be larger than 30 or the population data must be normally distributed. D. np^10np^10 and n(1p^)10n(1p^)10 E. Each observation must be independent of the other observations in the data set.

3. Select the null and alternative hypotheses the science educators should use to answer their research question.A. H0:p^=0.8178H0:p^=0.8178, HA:p^0.8178HA:p^0.8178 B. H0:p=0.7722H0:p=0.7722, HA:p>0.7722HA:p>0.7722 C. H0:p=0.7722H0:p=0.7722, HA:p0.7722HA:p0.7722 D. H0:p^=0.7722H0:p^=0.7722, HA:p^0.8178HA:p^0.8178 E. H0:p=0.7722H0:p=0.7722, HA:p<0.7722HA:p<0.7722

4. Calculate the test statistic. ? z t X^2 =

5. Calculate the p value.p-value =

6. A different group of government officials decide to replicate this research and conduct the hypothesis test with a different sample of adults living in Cameroon. The results of this hypothesis test give a p-value of 0.0006.These government officials have ? Little Some Strong Very Strong Extremely Strong evidence that the null model is not a good fit for their observed data.
