Which one of the following scenarios would the use of nonparametric procedures not be appropriate?

A) If the level of data measurement for the sample is only nominal or ordinal.
B) When calculating a confidence interval for the mean of a population when the population's standard deviation is not known.
C) When the sample size is very small (less than 30 ) because it will be difficult to test if the population is normally distributed.
D) When there is no corresponding parametric procedure for the hypothesis test, such as a test needed to estimate the median of a population.

Question 2

When testing for the significance of the overall regression model, the null hypothesis claims that there is a relationship between the dependent and independent variables.
