Answer:
Null hypothesis:
Alternative hypothesis: Not all the means are equal
The best option for this case would be:
H0:μ1=μ2=μ3=μ4
Ha: at least one of the means is different
Step-by-step explanation:
Previous concepts
Analysis of variance (ANOVA) "is used to analyze the differences among group means in a sample".
The sum of squares "is the sum of the square of variation, where variation is defined as the spread between each individual value and the grand mean"
Solution to the problem
For this case we are trying to proof if the mean number of courses taken in a college semester is different for freshmen, versus sophomores, versus juniors, versus seniors.
Based on this case we can set up the following system of hypothesis:
Null hypothesis:
Alternative hypothesis: Not all the means are equal
The best option for this case would be:
H0:μ1=μ2=μ3=μ4
Ha: at least one of the means is different
In order to find the number times something is larger than something, you have to use division where you divide the larger number by the smaller number.
So:
I'm not sure how much you want to round to, but the answer is 387.6063183 times.
You can make sure by multiplying the smaller number by 387.6063183 and you should get the larger number:
The price of each ball in a baseball bag would be 1.665 dollars
It is given that,
The cost price of a bag of baseball bag = 9.99 dollars
The number of balls in each bag = 6 baseballs
Now, we need to find the cost of one baseball if it were to sold individually
To find the cost of one quantity out of a bunch we divide the bunch price with the number of quantities in the bunch
Here, in this case
The cost price of each ball =
=
= 1.665 dollars
Hence, the price of each ball in a baseball bag would be 1.665 dollars
