When using a two sample test of means with equal standard deviations, then T distribution is the best option for it.
Sample test:
Sample test refers a method of reaching a conclusion to reject or support the claims based on sample data.
Given,
Here we need to identify in which of the following are assumptions made when using a two sample test of means with equal standard deviations.
While we looking into the options for this one, then we have identified that, the sampling distribution of the difference of means is a T distribution.
So, the populations have equal but unknown standard deviation's.
Therefore, we "pool" the sample standard deviation.

Answer:
2.3
Step-by-step explanation:
Using SOH CAH TOA, we can label CB as the alternate side seeing as it's opposite to the known angle 50 degrees. We know AB is the hypotenuse since it's the longest side. Therefore CA must be the alternate side.
Since we want to know BC, and we know information about AB, we need to use the use of the hypotenuse and the opposite. In SOH CAH TOA, SOH uses both of these.
Using S O H, we understand that sin(50) * 3 = CB
Therefore CB = 2.3 to 1 decimal place.
Volume of 1 ball = 4/3 π r³ = 4/3 (3.14) (2.25 ÷ 2)³ = 5.961 in³
Volume of 3 balls = 5.961 x 3 = 17.883 in³
Volume of cylinder = πr²h = (3.14) (2.25 ÷ 2)² (6.75) = 26.825 in³
Empty Space = 26.825 - 17.883 = 8.94 in³ (nearest hundredth)
Answer: 8.94 in³
Answer:
x>1
Step-by-step explanation:
x + 18 > 19
Subtract 18 from each side
x + 18-18 > 19-18
x>1
Answer:
Amount of people to serve x Serving Size = Size of ham
12 x 6.5 = ?
=78
Step-by-step explanation:
Looking for size ham chen should buy = ?
Amount of people to serve = 12
Serving Size = 6.5-ounce
Equation=
Amount of people to serve x Serving Size = Size of ham
12 x 6.5 = ?
=78
