ANS-
a) Restaurant tipping is the variable which is taken on x-axis in histogram.
b) sample size n = 41
c) A histogram is a plot that lets you discover, and show, the underlying frequency distribution (shape) of a set of continuous data. This allows the inspection of the data for its underlying distribution (e.g., normal distribution), outliers, skewness, etc.
Here mean= 18.302034
The Histogram graph gives a quick visual summary of the data. It is easy to see that the average tipping is around 18.302034. figure has no shape that can be defined. The only defining characteristic about this distribution is that it has 2 peaks of the same height. This means that the distribution is bimodal.
Median = 17.844456
The median is the middle value; uniformly spread data will provide that the area of the histogram on each side of the median will be equal.
Range = 44.112288
the range of a set of data is the difference between the largest and smallest values of Restaurant tipping where minimum value= 5.88 & maximum value = 49.996
d) value of third quartile Q3 = 21.23 which devided the whole data into four equal parts.
