Answer:
A. 31
B. 5
C. 9/31 or 0.29%
D. 2/31 or 0.06%
E. 0 or unknown
Step-by-step explanation:
A is the addition of all the entries, B is the number of entries that said snakes, C and D are about how many out of the total can give you the corresponding animal, chances are always part/total so for C it's 9/31 and D is 2/31. E is 0 or unknown because there is no "Frog" entries as favorite pet so it must be either 0 or unknown because you don't get the information

The probability that a face card can be drawn from a standard deck of cards is 12/52 which can be simplified into 3/13.
The expected value is the product of the probability and the value.
Expected value = (3/13)($1) = $0.23
The difference between the amount spent and the expected value is equal to $0.27.
Answer:
155 women must be randomly selected.
Step-by-step explanation:
We have that to find our
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Z-table as such z has a p-value of
.
That is z with a pvalue of
, so Z = 1.645.
Now, find the margin of error M as such
In which
is the standard deviation of the population and n is the size of the sample.
The population standard deviation is known to be 28 lbs.
This means that 
We want 90% confidence that the sample mean is within 3.7 lbs of the populations mean. How many women must be sampled?
This is n for which M = 3.7. So






Rounding up:
155 women must be randomly selected.
