If the majority of all students own a dog, then more than 50% own a dog. In this question we are comparing the population proportion for all World Campus STAT 200 students (i.e. p) to the value of 0.5. This is a single sampling proportion test. We want to know if the proportion is greater than 0.5, so this is a right-tailed test.To conduct a two-tailed randomization test using StatKey to determine if there is evidence that the mean housing cost for Big 10 schools is different than $3500, follow these steps: Upload the data set provided (Big 10 Mean Housing) into StatKey.

StatKey was used to construct a 95% confidence interval using the percentile method: In a sample of 200 World Campus students, 120 owned a dog. StatKey was used to construct a 95% confidence interval using the percentile method: In each of the examples the proportion of dog owners was \(\widehat p = 0.60\). The difference was the sample size.Test Statistic: One Group Mean. t = x ― − μ 0 s n. x ― = sample mean. μ 0 = hypothesized population mean. s = sample standard deviation. n = sample size. Note that structure of this formula is similar to the general formula for a test statistic: s a m p l e s t a t i s t i c − n u l l v a l u e s t a n d a r d e r r o r. 3.[Back to Statkey.no] Is the response variable continuous?
