Answer:
Step-by-step explanation:
Let X be the SRS scores of students.
Given that X is normal with standard deviation about 6.5.
Mean difference = is desired
i.e. Z score should be
Std error = std deviation of sample = 0.447
b)
So std error must be 0.997 and sample size must be atleast 193 to get the difference of x bar and mu to lie within 1.3 points in either direction
The height of each soup can is 4.138 centimeters, if the the volume of soup to be 325 cubic centimeters per can and the area of the base of each can is 25 square centimeters.
Step-by-step explanation:
The given is,
The volume of soup to be 325 cubic centimeters per can.
The area of the base of each can is 25 square centimeters.
Step: 1
Formula to calculate the volume of cylidrical soup can,
............................(1)
Where, B - Base area of cylidrical soup can
h - Height of cylindrical soup can
Step: 2
From the given values,
Base area, B = 25 square centimeters
Volume, V = 325 cubic centimeters
Equation (1) becomes,
325 = ( 25 ) (h)
h =
= 13 centimeters
Height of cylindrical soup can, h = 13 centimeters
Result:
The height of each soup can is 4.138 centimeters, if the the volume of soup to be 325 cubic centimeters per can and the area of the base of each can is 25 square centimeters.
