It all depends. You've given us an incredibly vague question.
The outlier could be a number that's low or quite high. Also, outliers
shouldn't really contribute towards the value of the mean, median or
range related to a group of data.
They are called outliers because they are bizarre results or numbers
and should be detached from groups of data. Outliers by definition
are abnormalities or anomalies.
I'd say outliers don't really change anything, unless you actually want
to give them credibility or weight.
Large outliers can inflate the value of means, medians and ranges.
Small outliers will invariably deflate the value of means and medians.
This is the equation for this problem.
The first scatter plot does not have a zero correlation.
Option(a) is correct.
A statistic called correlation gauges how much two variables change in connection to one another.
Correlation quantifies correlation but cannot determine whether x causes y or vice versa, or whether a third component is responsible for the association.
A scatterplot may make it easier to spot correlation, particularly when the variables have a non-linear but nevertheless significant association.
Zero means there is no correlation between the two variables under comparison.
A 0 correlation indicates that there is no relationship between the two variables according to the correlation statistic. This merely indicates that there isn't a linear relationship, not that there isn't any link at all. The first scatter plot does not represent a linear relationship, thus, it has zero correlation.

Take away the 60 minutes for Saturday: 225 minutes. In the week there were 225/45=5 classes.
The equation is no. of classes=(285-60)/45.
