Answer: 2.77777778
Step-by-step explanation:
25/9=2.77777778
check
2.77777778*9= 25 dollars
We are going to use a continuity correction factor. When you use a normal distribution to get the estimated binomial distribution, you're going to have to use a continuity correction factor. So with this, the data will become from <span>20 - 35 it will now become 19.5 to 35.5.
So we are going to use the z table for this problem. So if we are looking for the z value, the formula would be: </span>x – μ / σ<span>
get the value of the first z value:
</span>z1 = (19.5 - 30) / 9 = -1.167
get the value of the second z value:
<span>z2 = (35.5 - 30) / 9 = 0.61
</span>
So getting the probability of both:
P(-1.167 < z < 0.61) = P(Z ≤ b) – P(Z ≤ a) = <span>0.6075</span>
Its the last one! Also if you dont know what I mean by this is, its the 4th one. You Welcome Merry Christmas
The answer is 4.6666,I hope it helps I’m not sure if it’s right
