12% offer one honors class, 25% offer two honors classes, 20% offer three honors classes, and 5% offer four honors classes.
A high school is selected at random. What is the probability that it offers an even number of honors classes?

Using the discrete distribution, it is found that the probability that it offers an even number of honors classes is of 0.68.

<h3>What is the discrete probability distribution?</h3>

The distribution for the number of honors classes the school offers is given by:

  • P(X = 0) = 0.38
  • P(X = 1) = 0.12.
  • P(X = 2) = 0.25.
  • P(X = 3) = 0.2.
  • P(X = 4) = 0.05.

Hence the probability of an even number is given by:

P(even) = P(X = 0) + P(X = 2) + P(X = 4) = 0.38 + 0.25 + 0.05 = 0.68.

Solve the following equation
san4es73 [151]
The first step to solving this is to write the number in exponential form
2^{-IxI} = 2^{7}
since the bases are the same,, set the exponents equal to one another
-IxI = 7
now change the signs on both sides of the equations
IxI = -7
this equation is false for any value of x because the absolute value function needs to always be positive or 0,, which is not the case for this expression
x ∈ ∅
this means that the answer to your question is x ∈ ∅
let me know if you have any further questions

Neporo4naja [7]

Answer:

B) No, because the p-value is greater than any reasonable significance level

Step-by-step explanation:

H-null: p = 0.41

H-alt: p =/= 0.41

1 proportion Z test

On a calculator: stat + tests + 5

   p: .41

   x: 245

   n: 600

   prop: =/= p

This gives a p-value = .934

(standard significance level is .05, so this p-value is much larger)
