Answer:
4 and 6
Step-by-step explanation:
These are the points in which y=0
(a) someone over 55
mean, mu = 22
standard deviation, sigma = 2
X=19
Z(X)=(X-mu)/sigma=(19-22)/2=-1.5
P(x>X)=1-P(x<X)=1-0.0668072=0.9331928
Therefore probability for a 55-year old to find a job in over 19 weeks is 0.9332
All we need to do is to find a common denominator for both 1/2 and the other numbers individually:
1/2 = 3/6 (so 3/6 is not less than 1/2 - both numbers are equal)
1/2 = 15/30 and 7/15 = 14/30 (so 7/15 is less than 1/2)
1/2 = 9/18 and 4/9 = 8/18 (so 4/9 is less than 1/2)
1/2 = 4/8 (so 5/8 is not less - it's greater than 1/2)
Answer: From the list above only <u>7/15 and 4/9</u> are less than 1/2.
Answer: The first question is the first option and the second one is is explained below:
