- A test of H0: μ = 53 versus H1: μ ≠ 53 is performed using a significant level of α = 0.01. The P-value is 0.033. if the true value of μ is 53, does the conclusion result in type I error, a type ii error, or a correct decision? A). Type ii error B). correct decision C). Type i errorExpress the null hypothesis and the alternative hypothesis in symbolic form. Use the correctsymbol (µ, p, Η) for the indicated parameter. An entomologist writes an article in a scientific journalwhich claims that fewer than 16 in ten thousand male fireflies are unable to produce light due to agenetic mutation. Use the parameter p, the true proportion of fireflies unable to produce light.If my null hypothesis is ‘Dutch people do not differ from English people in height’, what is my alternative hypothesis? a) English people are taller than Dutch people. b) none of the choices c) Dutch people differ in height from English people. d) Dutch people are taller than English people.
- Express the null hypothesis and the alternative hypothesis in symbolic form. Use the correct symbol (μ, ρ, σ) for the indicated parameter. A psychologist claims that more than 5.8 percent of the population suffers from professional problems due to extreme shyness. Use p, the true percentage of the population that suffers from extreme shyness. Group of answer choices H0 : p = 5.8%H1 : p ≤ 5.8% H0 : p = 5.8%H1 : p < 5.8% H0 : p = 5.8%H1 : p > 5.8% H0 : p = 5.8%H1 : p ≥ 5.8%express the null hypothesis and the alternative hypothesis in symbolic form. Carter Motor Company claims that its new sedan, the Libra, will average better than 28 miles per gallon in the city. Use u, the true average mileage of the Libra.A test of hypothesis is statistic H0: u=150 versus H1:u greater than 150 was performed. The P-value was 0.035. Fill in the blank: If u=65, then the prpbability of observing a test as extreme as or more extreme than the one actually observed is ________________.
- The USDA limit for salmonella contamination for chicken is 20%. A meat inspector reportsthat the chicken produced by a company exceeds the USDA limit. You perform a hypothesis testto determine whether the meat inspector’s claim is true.When will a type I error occur? Explain using the above contextFor the given scenario determine the type of error that was made, if any .(hint begin by determining the null and alternative hypothesis. )A cell phone company claim only $50 as the main amount to its customers spend on cell phone service per month. One skeptical customer claims that the main amount its customers being on a cell phone service per month is different from $50. The skeptical consumer conduct a part of this test and fails to reject the null hypothesis. Assume that in reality the main amount its customers stand on cell phone service per month is $45. Was an error made? If so what type.Decide whether to reject or fail to reject the null hypothesis and (e) interpret the decision in the context of the original claim
- choose the corect answer and give brief explaination, this simple question thats why i make it as one question PT. ABCD has factories in 2 locations, namely in New York and New Jersey. To test whether there is a difference in the daily productivity of the two factories, a sample of 20 days of production was taken from each factory. Then the hypothesis being tested is ... Ho: u1 = u2 vs Ha: u1 > u2 All of the above is true Ho: u1 = u2 vs Ha: u1 not the same as u2 Ho: u1 = u2 vs Ha: u1 < u2 Of a random sample of 64 businessmen, 48 were classified as "successful". If it is known that the population proportion is 0.70, then the standard error of the proportion estimator is 0.0772 0.8728 0.0572 0.0033The mechanics of a paired tt-test are very similar to a Student's tt-test.Also determine the test statistic and the P value State the final conclusion that addresses the original claim.
