You believe both populations are normally distributed and that the population standard deviations are known. You obtain a sample of size ₁ = 42 with a mean of ₁ = 50.1 and a population standard deviation of o₁ = 11.6 from the first population. You obtain a sample of size n₂ = 53 with a mean of ₂ = 53.2 and a population standard deviation of o2 = 9.5 from the second population. What is the test statistic for this sample? (Report answer accurate to three decimal places.) test statistic = What is the p-value for this sample? (Report answer accurate to four decimal places.) p-value = The p-value is... O less than (or equal to) a Ogreater than a This test statistic leads to a decision to... O reject the null O accept the null O fail to reject the null
