Answer:
Probability of the day to be a snow day is 0.34
Step-by-step explanation:
We have the data,
Out of 21 which had less than 3 inches of snow, 5 were snow days.
Out of 8 days which had more than 3 inches of snow, 6 were snow days.
So, we get,
Total number of days = 21 + 8 = 29
Total number of snow days = 5 + 6 = 11
Thus, the probability that the day will be a snow day is  i.e. 0.34
 i.e. 0.34
Hence, the probability of the day to be a snow day is 0.34.
 
        
             
        
        
        
Answer:
b) B and D and c) A and C
Step-by-step explanation:
The hypotheses would be:

(Right tailed test at 5% level)
Sample proportions are
Sample              A                 B                C                 D
Success            31               34               27               38
Proportion p     0.775         0.85            0.675          0.95
Std error
(sqrtpq/n)          0.066        0.056          0.074          0.034
p diff
p-0.75               0.025        0.10             - 0.075        0.20
Z stat                  
p diff/SE            0.0757       1.77                 1.01          5.80
p value               0.469       0.038             0.156       0.000001
we find that p value is more smaller than alpha, the more accurate the alternate hypothesis.
b) Only B and D provide against the null.  Because p <0.05
c) A and C provide no evidence for the alternative because p >0.05
 
        
             
        
        
        
For large candles, the price is $10. They sold 42, we can say that. 42*10 is the total price or revenue without the cost to make the candles included. The cost to make the candles is $x. So we can say profit for large candles = (420 - 42x).
For small candles. The price is $5 and 56 are sold. The cost is again $x. So the profit for small candles is (280 - 56x).
So the total profit for part one of your question is (420 - 42x) + (280 - 56x).
In part to we are told that large candles cost $5 and small candles cost $3. Substituing this into are expression gives (420 - 42(5)) + (280 - 56(3)). This gives us $322. So the total profit is $322.
