20 students' heights were measured for statistic analysis, with the following results:
female 5'6, female 5'8, male 5'9, male 5'6, female 5'7, female 5'5, female 5'6, male 5'10, male 5'8, female 5'4, female 5'4, male 5'9, female 5'1, female 5'5, male 5'11, male 5'7, female 5'6, female 5'8, male 6'1. male 5'9
Please return a report with the following components:

The solution provides a page report on the distribution of students' heights by gender in Word including histograms, mean, median, mode, standard deviations, variance and results analysis for each gender with the gender differences and their significance (complete with confidence interval calculations) at the end. Workings are included as an Excel spreadsheet.
