Step 1. You need to convert your height(if given in 'cm') into' inches' if mean and standard deviation are in 'inches'

or

  You need to convert your height(if given in 'inches') into' cm' if mean and standard deviation is in 'cm'.

===================================================================================

Conversion into 'cm' if mean and std are in 'cm'

EX- suppose your height = 5ft 10 inches = 5*12+10=70 inches

since 1 ft = 12 inches

70 inches = 70*2.54 cm = 177.8 cm (1 inche = 2.54 cm)

Suppose the mean height = 165cm and stdev = 4cm

Suppose you want to test the notion that individuals perceive a greater height difference between men and women than actually exists, due to stereotyping. The true population difference between the height of men and women is an average of 5 inches. You obtain a random sample of 400 individuals and record their perceptions of the mean difference in height between men and women. You find that the sample perceives the difference between men and women to average 6 inches. The...

Suppose you want to construct a 99% confidence interval for the average height of US males above the age of 20. Based on past studies you think the standard deviation of heights for this population is around 6 inches. How large a sample should you gather to ensure that your confidence interval has a width no greater than 1 inch?

I need a calculation f a female that's 5.6 inches tall The average height for all males is 69.3 inches with a standard deviation of 2.8 inches. For females, the average height is 64 inches and the standard deviation is 2.8. These are population values. For this week’s discussion, you will calculate a z-score based on your own height and determine whether your score is within the 95% normal range or if it is out of that range and considered...
