WebGiven data from two samples, we can do a signficance test to compare the sample means with a test statistic and p-value, and determine if there is enough evidence to suggest a … WebThe mean difference = 1.91, the null hypothesis mean difference is 0. Standard deviation is 0.617. Z = (0-1.91)/0.617 = -3.09. It takes -3.09 standard deviations to get a value 0 in this distribution. which when converted to the probability = normsdist (-3.09) = 0.001 which indicates 0.1% probability which is within our significance level :5%.

Usually the term "discrete" would apply to a random variable (numeric rather than distinct categories of things), which took a countable number of distinct values. An example of a discrete variable is a count (counts clearly satisfy the requirement of being countable). WebHa: There is a difference between the sample mean and a known population mean. OR H0: mean = 120 Ha: mean x 120 Computing the test statistic: t = sample mean - population mean / (standard deviation / 𝑛)n = sample size.
