Answer:
C
Step-by-step explanation:
To find the appropriate equation, notice the red graph has shifted up about 6 units. This means that which is shifted by -3 will move 6 up. -3+6= 3. This means the function will have +3. Only B and C are options. Now test a point. Notice the red function crosses the y-axis at about 5 or 6 when x=0.
This function doesn't match.
This function matches. Option C is correct.
Answer: a) The probability is approximately = 0.5793
b) The probability is approximately=0.8810
Step-by-step explanation:
Given : Mean :
Standard deviation :
a) The formula for z -score :
Sample size = 1
For x= 63 in. ,
The p-value =
Thus, the probability is approximately = 0.5793
b) Sample size = 35
For x= 63 ,
The p-value =
Thus , the probability is approximately=0.8810.
