Answer:
Median: 11
Range: 12
25th percentile: 9
75th percentile: 14
Interquartile range: 5
Step-by-step explanation:
✔️Median = the value that lies at the point where the vertical line divides the box into two = 11
✔️Range = max value - min value = 19 - 7 = 12
✔️25th percentile = Q1 = the value at the beginning of the edge of the rectangular box = 9
✔️75th percentile = Q3 = the value at the end of the edge of the box = 14
✔️ Interquartile range = Q3 - Q1 = 14 - 9 = 5

Answer: 7410 watches
Step-by-step explanation:
From the random sample of 250 watches, 3 are defective. The percentage that's defective will be:
= 3/250 × 100
= 1.2%
Percentage that's not defective = 100 - 1.2 = 98.8%
Therefore, from the sample of 7500 watches, the number that's not defective will be:
= 98.8% of 7500
= 98.8/100 × 7500
= 7410
Therefore, 7410 watches aren't defective
