Figure 1: Histogram for arrival time
2)
The obtained histogram, it has been observed that right hand side of it is almost mirror
image of the left hand side. From the histogram, it can therefore be said that the distribution is
close to symmetric or normal distribution (Fisz & Bartoszynski, 2018)

Table 1: Descriptive Statistics for arrival time
4)
The table presenting descriptive statistics shows that average arrival time is 14.01. That
means that on an average it takes 14 days for a package to arrive in Australia. The standard
deviation of the distribution is 5.97. Obtained standard deviation is lower than average arrival
time indicating distribution of arrival time has less variability (Hinton, 2014). The median of the
distribution is 14 days. The modal value of the distribution is 17 implying in most of the sample
cases selected, it takes 17 days for a package to arrive at destination. The value of skewness is
close to 0 meaning an almost symmetric distribution.
