A linear equation would be the best fit, but the last point (-1,-7) kinda messes it up. If the -7 would have been a -6 the line y=-2x-8 would fit perfectly.
The mean is affected by an outlier...lets find out how...
example : (2,3,4,5,30)
the outlier is 30
the mean is :(2 + 3 + 4 + 5 + 30) / 5 = 44/5 = 8.8
now lets take out the outlier of 30...and find the mean
(2 + 3 + 4 + 5) / 4 = 14/4 = 3.5
therefore, a single outlier can cause the value of the mean to move slightly towards the outlier
Answer:
Yes, It is an binomial experiment.
Step-by-step explanation:
Consider the provided information.
There are 4 conditions to identify that a distribution is binomial or not.
- Binary: That means only two possibility success or failure.
- Fixed number of trials.
- Independent trials.
- The probability of success is constant from trial to trial.
Now consider the provide procedure:
Binary condition is satisfied because baby can be male or not.
Trials are independent because couples were selected randomly. It satisfy the 2nd condition.
There are 70 couples it satisfy the 3rd condition.
Probability of success will be constant as couples selected randomly. It satisfy the 4th condition.
Yes, It is an binomial experiment because procedure satisfies all the criteria for a binomial distribution.
Hence, It is an binomial experiment.
3 types breakfast
2 types drink
3*2 = 6 breakfast drink combos
where the eggs and juice is 1 of those 6
probability is 1/6
Answer:
y = 4
Step-by-step explanation:
4*y = 4y
4*4 = 16
4y+16=32
to get 4y alone, we subtract 16 from 32.
32-16 = 16
4y = 16
to get y alone, we divide 4 by 16
16/ 4 = 4
so, y = 4
