Statistics finding

Create a simple distribution graph (histogram) where we will explore the age of women after giving birth to their first child. Remember that a histogram consists of parallel vertical bars that show the frequency distribution of a quantitative variable in the graph. 

Determine the mean of the age of the women in the Gestation Demographics SEU dataset. (Walpole, 1982).

Test the hypothesis that the mean age (μ = μ0) for women is 37 years in the Gestation Demographics SEU dataset. (Walpole, 1982).

P value is less than 0.05 so we reject the null hypothesis and conclude that mean value is not equal to 37. The result is insignificant
