When a coin is tossed, then sample space consists of: STA301

Yes, when a coin is tossed, the sample space consists of 2 possible outcomes.

The sample space represents all the possible outcomes of an experiment. For a single coin toss, the possible outcomes are:


S = {\text{Heads (H)}, \text{Tails (T)}}

So, the sample space has 2 outcomes: Heads and Tails. Hence, the number of elements in the sample space is 2.

In a Box and Whisker plot, if the median line is closer to the left of the box then distribution will be: STA301

In a Box and Whisker plot, if the median line (which represents the second quartile, or Q2) is closer to the left of the box, it indicates that the data is positively skewed (also known as right-skewed).

This means:

• The majority of the data points are concentrated on the lower end of the range.
• There is a longer tail towards the higher values (right side of the distribution).
• The right side of the box (between Q2 and Q3) is wider than the left side (between Q1 and Q2), indicating that the upper half of the data is more spread out.

Thus, the distribution will be positively skewed.
