Question 26
The daily sales of choco-chip ice-creams in an ice-cream parlour is assumed to follow a Normal distribution with a mean of 5 and a variance of 4. To check the assumption of normal distribution, the sales of choco-chip ice-creams at the ice-cream parlour for 7 days was collected (Table-1). On all 7 days, the total number of ice-creams (of all flavours) sold per day was 100. With this data, answer the given subquestions.
{Note: Round all your calculations (intermediate and final) to one decimal place}
| Day | The actual number of choco-chip ice-creams sold |
|---|---|
| Day-1 | 12 |
| Day-2 | 14 |
| Day-3 | 12 |
| Day-4 | 13 |
| Day-5 | 12 |
| Day-6 | 11 |
| Day-7 | 12 |
