Answer:
a. 5.26
Step-by-step explanation:
As, the standard deviation of the distribution of the difference between mean is 0.76 so the t score will be simply calculated by dividing the difference of means by standard deviation of the distribution of the difference between mean as hypothesized difference is zero.
t score=Xbar A- Xbar B/Sd of difference of means
t score=55-51/0.76
t score=4/0.76=5.26
Answer:
its already in its simplest form.

Answer: the diameter of the hydrochloric acid in Casey's container is 6 inches
Step-by-step explanation:
The formula for determining the volume of a cylinder is expressed as
Volume = πr²h
Where
r represents the radius of the cylindrical beaker.
h represents the height of the cylindrical beaker.
π is a constant whose value is 3.14
From the information given,
Volume cylindrical beaker = 113 cubic inches.
Height = 4 inches
Therefore,
113 = 3.14 × r² × 4
113 = 12.56r²
r² = 113/12.56 = 8.9968
r = √8.9968
r = 3
Diameter = 2 × radius
Diameter = 2 × 3 = 6 inches
