A data analyst wants to set up a hypothesis test to determine if the mean number of courses taken in a college semester is diffe

rent for freshmen, versus sophomores, versus juniors, versus seniors. Label these four groups of students as years 1, 2, 3, and 4. What would be the correct setup for the null and alternative hypotheses for this test?

Answer:

Step-by-step explanation:

Hello!

What you want to test is if there is a difference between the number of courses taken by students of different years, you can determine 4 populations of students:

Population 1: Freshmen

Population 2: Sophomores

Population 3: Juniors

Population 4: Seniors

To each population you measured the study variable, setting 4 different variables. To compare these variables the best way is to make one test where you compare the four populations at the same time, so the hypothesis is:

H₀: μ₁ = μ₂ = μ₃ = μ₄

H₁: At least one of the population means is different from the others.

The most appropriate test to use to compare the population mean of the 4 groups is an ANOVA.

I hope you have a SUPER day!

Answer:

2 1/2 I think

Step-by-step explanation:

you find the L.C.M for all the fractions and multiply it. You should end up with whole numbers.

It should look like this

2n+3n=2

n= <u>2n+3n</u><u> </u> = <u>5</u>

2 2

n= 2 1/2

How many terms are in the binomial expansion of (2x 3)5? 4 5 6 7
padilas [110]

In the binomial expansion (2x + 3)^5 , there are 6 terms.

According to the question, given that

Binomial expansion  (2x + 3)^5

Number of terms in a binomial expansion of (x + y)^n is

N = n + 1 words in total

In the binomial expansion (2x + 3)^5

n = 5

N = 5 + 1 = 6

Therefore, In Binomial expansion  (2x + 3)^5 there are 6 terms.

The algebraic expression (x + y)n can be expanded according to the binomial theorem, which represents it as a sum of terms using separate exponents of the variables x and y. Each word in a binomial expansion has a coefficient, which is a numerical value.

The formula for expanding the exponential power of a binomial expression is provided by the binomial theorem, sometimes referred to as the binomial expansion. The following is the binomial expansion of (x + y)n using the binomial theorem:

(x+y)^n = n_C_{0} * n_y_{0} + n_C_{1}  * n-1_y_{1} + n_C_{2} * n-2_ y_{2} + ... + n_C_{n-1} * 1_y_{n-1} + n_C_{n} * 0_y_{n}
