Hypothesis Testing using z-test
What is the standard error of the mean for a distribution of scores where the standard deviation for the population = 15 and the size of the sample = 100?
The Z test is appropriate statistical test when sample size is
A test is conducted for H0: μ = 34, with σ = 5. A sample of size 100 is selected. The standard error of the sampling distribution is
A test is conducted for H0: μ = 20, with σ = 4. A sample of size 36 has sample mean as 21.4. The test statistic is
A test is conducted for H0: μ = 50 v/s. H1: μ > 50. The test statistic is 2.46. The p‐value is
