Use the normal distribution and the given sample results to complete the test of the given hypotheses. Assume the results come from a random sample and use a 5% significance level. Test H0: p = 0.25 vs Ha: p < 0.25 using the sample results p̂p^= 0.13 with sample size n = 100. The standard error of the sample statistic in this situation is 0.043. Round your answer for the test statistic to two decimal places. What is the p-value?...

Answer A and B for first question
A genetic experiment with peas resulted in one sample of offspring that consisted of 447 green peas and 164 yellow peas. a. Construct a 90% confidence interval to estimate of the percentage of yellow peas. b. It was expected that 25% of the offspring peas would be yellow. Given that the percentage of offspring yellow peas is not 25%, do the results contradict expectations? a. Construct a 90% confidence interval. Express the percentages...

Current Attempt in Progress Use the normal distribution to find a confidence interval for a difference in proportions p 1 -p 2 given the relevant sample results. Assume the results come from random samples. A 90% confidence interval for p 1 -p 2 given that p^1 = 0.25 with n 1 = 60 and p^2 = 0.40 with n 2 = 80 Give the best estimate for p 1 -p 2, the margin of error, and the confidence interval. Round...

a) Use the t-distribution to find a confidence interval for a difference in means μ1-μ2 given the relevant sample results. Give the best estimate for μ1-μ2, the margin of error, and the confidence interval. Assume the results come from random samples from populations that are approximately normally distributed. A 90% confidence interval for μ1-μ2 using the sample results x¯1=8.8, s1=2.7, n1=50 and x¯2=13.3, s2=6.0, n2=50 Enter the exact answer for the best estimate and round your answers for the margin...
