Alena has a pair of dogs, and she noticed they usually breed more male puppies than females. To check that, she bred them again and obtained 15 puppies, and 13 of them were males.
Let's test the hypothesis that each puppy has an equal chance of 50% of being either male or female versus the
alternative that the chance of a male puppy is greater.
The table below sums up the results of 1000 simulations, each simulating 15 puppies with a 50% chance of
being male or female.
According to the simulations, what is the probability of having 13 male puppies or more out of 15?

step-by-step explanation:

this is because the profit is decreasing and turning into debt

0 and 5 minutes

step-by-step explanation:

given that one morning eight buses arrive late by the number of minutes given below:

0 8 2 6 9 2 0 7 8

write these in ascending order

0   0 2 6 7 8 8 9

in the afternoon two more buses arrive at the bus stop say by x and y minutes late.

total number of buses = 10

median = average of 4th and 5th after arranging in ascending order

since 4th entry is 6, the values of x and y should be below 6

also given 0 is the mode so either x or y or both should be 0 because then only 0 gets the maximum frequency and hence mode

thus we have

0 0 0 2 6 7 8 8 9 and another unknown entry which is below 6.

since median is 3.5, we have the unknown entry to be 5 only because then only median =( 2+5)/2

thus the after noon buses were late by 0 and 5 minutes.

yes, whats the problem?
