You wish to test the following claim (HaHa) at a significance level of α=0.001α=0.001.      Ho:p1=p2      Ha:p1≠p2You obtain 94% successes in a sample of size n1=796n1=796 from the first population. You obtain 97.9% successes in a sample of size n2=329n2=329 from the second population. For this test, you should NOT use the continuity correction, and you should use the normal distribution as an approximation for the binomial distribution.What is the test statistic for this sample?

n a certain school district, it was observed that 30% of the students in the element schools were classified as only children (no siblings).  However, in the special program for talented and gifted children, 147 out of 422 students are only children.  The school district administrators want to know if the proportion of only children in the special program is significantly different from the proportion for the school district. Test at the α=0.05α=0.05 level of significance.What is the hypothesized population proportion for this test? p=p=  (Report answer as a decimal accurate to 2 decimal places.  Do not report using the percent symbol.)Based on the statement of this problem, how many tails would this hypothesis test have? one-tailed test two-tailed test Choose the correct pair of hypotheses for this situation: (A) (B) (C) H0:p=0.3Ha:p<0.3 H0:p=0.3Ha:p≠0.3 H0:p=0.3Ha:p>0.3   (D) (E) (F) H0:p=0.348Ha:p<0.348 H0:p=0.348Ha:p≠0.348 H0:p=0.348Ha:p>0.348 (A) (B)…

The numbers of online applications from simple random samples of college applications for 2004 and for the 2009 were taken. In 2004, out of 491 applications, 206 of them were completed online. In 2009, out of 268 applications, 145 of them were completed online. Test the claim that the proportion of online applications in 2004 was equal to the proportion of online applications in 2009 at the .10 significance level.Claim: Select an answer  p 1 > p 2  u 1≠u 2  p 1≠p 2  u 1 < u 2  p 1 ≥ p 2  u 1 = u 2  p 1 = p 2  u 1 ≥ u 2  p 1 < p 2  p 1 ≤ p 2  u 1 > u 2  u 1 ≤ u 2   which corresponds to Select an answer  H1: u 1 < u 2  H0: p 1 ≤ p 2  H1: p 1 > p 2  H0: p 1≠p 2  H1: p 1 < p 2  H1: u 1 > u 2  H1: p 1≠p 2  H1: u 1≠u 2  H0: p 1 = p 2  H0: u 1 ≤ u 2 Opposite: Select an answer  u 1 < u 2  u 1 ≤ u 2  p 1 ≥ p 2  p 1 ≤ p 2  p 1 > p 2  p 1 < p 2  u 1 ≠ u 2  p 1 = p 2  u 1 < u 2  u 1 = u 2  u 1 > u 2  p 1≠p 2   which corresponds to Select an answer  H1: p 1≠p…
