Answer:
1. A: 0.25; B: 0.03; C: 1.41; D: -0.28
2. A: 0.39; B: 0.06; C: 40.30; D: 21.81
Step-by-step explanation:
For CDF lookups, we used the Excel NORMDIST(x, mean, stdev, TRUE) function. For inverse CDF lookups, we used the NORMINV(x, mean, stdev) function.
Each of these functions works with the area under the curve from -∞ to x, so for cases where we're interested in the upper tail, we subtract the probability from 1, or subtract the x value from twice the mean.
For question 1, we computed the Z values in each case. The NORMDIST function works directly with x, mean, and standard deviation, so does not need the z value.
<span>Yes, the two events are independent because P(NF|PB) = P(NF).
I'm not 100% sure though so wait til someone else answers :)</span>
The answer is C.
step one: add all 3 numbers. 25.
step 2: 200 divided by 25. 8.
step 3: 8 x all the other numbers ( separate ) 96, 64, 40.
step 4: add them. 200.
96 students want a beef meal, 64 chicken and 40 pasta.
If Jana wins the contest, she will get two movie tickets, and if she gets two movie tickets, she will take her mother to the movies.
If you think about this deductively, and if you have the knowledge of syllogisms, this won't be difficult to solve.
So, this is the conclusion:
If Jana wins the contest, then she will take her mother to the movies.
This is the conclusion given that if she wins the contest, she will get the tickets she needs to take her mother to the movies. Otherwise, that won't happen.
