Answer:
0.0084
Explanation:
For this probability problem, we will have to make use of the normal probability distribution table.
to use the table, we will have to compute a certain value
z = (x- mean) /Standard deviation
z = 
= 2.39
Probability he has worked in the store for over 10 years can be obtained by taking the z value of 2.39 to the normal probability distribution table to read off the values.
<em>To do this, on the "z" column, we scan down the value 2.3. we then trace that row until we reach the value under the ".09" column. </em>
This gives us 0.99916
Thus we have P (Z < 2.39) = 0.9916
We subtract the value obtained from the table from 1 to get the probability required.
1 - 0.9916 = 0.0084
The Probability that the employee has worked at the store for over 10 years = 0.0084
Answer:
UCL= <u>0.044</u>
LCL=<u>-0.004</u>
Explanation:
Use following formula to calculate the UCL and LCL
UCL = p + z
Where
P = defect rate = 2% = 0.02
z = sigma control chart limit = 3
n = samploe size = 300
PLacing values in the formula
UCL = 0.02+3
UCL = 0.02 + 3 x 0.008082904
UCL = 0.02 + 0.024248711
UCL = 0.044248711
UCL = 0.044
Now calculate LCL using folllowing formula
LCL = p - z
Where
P = defect rate = 2% = 0.02
z = sigma control chart limit = 3
n = samploe size = 300
PLacing values in the formula
LCL = 0.02 - 3
LCL = 0.02 - 3 x 0.008082904
LCL = 0.02 - 0.024248711
LCL = -0.004248711
LCL = -0.004

Answer:
B) use the observed data to form a hypothesis about ice cream buying behavior.
Explanation:
The scientific method is a research method where the first step is recognizing and identifying the problem ⇒ relevant information is obtained ⇒ a hypothesis is formulated ⇒ the hypothesis is tested.
In order for a research (that uses the scientific method) to be valid, the researcher must be able to duplicate the research process and obtain the same or similar results.
