Question 16
An ice cream seller has collected data on the number of ice-creams sold by him in two streets “A” and “B” over the past 15 days. This data is provided in Table-1. The number of ice creams sold in street “A” is expected to follow a uniform distribution. Based on the sample, you decide to perform a statistical test with the following bins [75 to 100), [100 to 125), [125 to 150), [150 to 175].
Given this information, answer the given subquestions.
| Number of Ice-Creams Sold in Street-A | Number of Ice-Creams Sold in Street-B | |
|---|---|---|
| Day-1 | 120 | 85 |
| Day-2 | 130 | 75 |
| Day-3 | 75 | 120 |
| Day-4 | 160 | 80 |
| Day-5 | 130 | 160 |
| Day-6 | 120 | 75 |
| Day-7 | 120 | 78 |
| Day-8 | 75 | 130 |
| Day-9 | 75 | 143 |
| Day-10 | 75 | 154 |
| Day-11 | 75 | 122 |
| Day-12 | 160 | 90 |
| Day-13 | 160 | 85 |
| Day-14 | 130 | 79 |
| Day-15 | 160 | 97 |
Table-1
If the aim is to find if the sales in “Street-A” and “Street-B” are independent on each other across days, then what is the expected sales on “Day-4” for “Street-B”? (Note: Enter the answer rounded to two decimal places. For example, if the answer is “1.234”, then enter it as “1.23”)
