<span>A) About 25% of the fishermen caught between 25 and 30 fish.
>Since the boxplot looks symmetric, the parts are each 25%.
</span><span>B) The spread is symmetrical about the median.
>The median is 20.
20-15 = 5; 15-10 = 5
25-20 = 5; 30-25 = 5
</span><span>E) The range is 20 fish.
> The largest data is 30, smallest data is 10
Range = largest - smallest = 30-10 = 20</span>
The point (4,7) is the only one that can be plugged into the equation and work. in this case when 4 is plugged in as X & Y is plugged in at 7 we get that 7=7, which is a true statement.
It most likely has a 0.3 chance
Answer:
A hostel has provision for 45 students for 30 days.If 15 more students joined the hostel after 6 days,how long will provision last?
z=(63-84)/3= -21/7= -3
P(x>63)=p(z > -3) = .9987 or 99.87%
