(d) mean>median<mode​

Answer 1

Answer:

The answer for this is a) mean=median=mode

Step-by-step explanation:

Normal distribution is a probability density function that is symmetrical about its median, mean and mode. You can think of the y-coordinates along the graph as the frequency of their corresponding x-coordinates . The highest point of the graph represents the highest frequency, and if you trace its x-value, it happens to sit in the middle of the graph, hence why mode(x-value that traces to the highest y-value on the graph) = median(middle x-value of the graph). Mean is harder to explain so I'll leave that to somebody else more capable than me to explain. Please refer to the shape of the graph as you read through my explanation for greater clarity.
