Step 1

Hey there! Thank you for posting the question. However, since your question has more than 3 parts, according to our policy, we have solved the first 3 parts for you. If you need help with any other part, please re-post the question and mention the part you need help with.

Step 2

1.

According to Chebyshev’s inequality, one can find the unusual value.

The probability of a data value to be more extreme than 4.76 standard deviations from the mean is less than 0.04. It can be considered as unusual data value because it is unlikely to happen.

According to empirical normal probability, a data value which is far away from the three standard deviations of the mean can be considered as unusual value and it has less probability of occurrence.

Step 3

2.

According to Chebyshev’s inequality, we have

The probability of a data value to be more extreme than –1.36 standard deviations from the mean is 0.54. It cannot be considered as unusual data value because the probability of happening is hi...
