Now we check the normality of data.

a. Lilliefors Significance Correction
with the help of Kolmogorov we come to know that mean of influence of window display is
normal because the significance level is greater than 0.05 and other variables is not
normal because there significance level is not greater than 0.05.
By using QQ plot and Histogram I only check the mean of influence so that I come to know that
is normal or not.

By seen Q-Q Plot and Histogram I come to know that data is normal
Now apply parametric test on normally variance data.

From the levene’s test for equality of variance the significance level of mean of influence of window
display us 0.903 which is greater than 0.05 which shows that the variance mean of influence of window
display are equal.
From t test for equality of mean the significance level of influence of window display is 0.170 which is
greater than 0.05 so we accept H0 that is µ1=µ2 which shows that male and female are equally influence
on influence of window display.

a. Grouping Variable: gender
Mean of impulse buying, advertisement and sales promotion and personal experience have
significance value 0.984, 0.573 and 0.204 respectively which are all less than 0.05 it mean we
accept H0 for all the 3 variables which shows that male and female both like impulse buying
behavior both male and female are attracted by advertisement and sale promotion and similarly
the personal experience of both male female are same.
