What is the decision regarding the differences between the observed and expected frequencies if the critical value of the chi-sq

uare is 9.488 and the computed chi-square value is 6.079 g
Mathematics

ra1l [238]3 years ago

Answer:

Accept the null hypothesis if it is two tailed test.

Step-by-step explanation:

The null hypotheses can only be accepted if it is a two tailed test and calculated chi square must be less than the critical value of chi square.

Then the difference between the  the observed and expected frequencies will be zero.

where

H0 : σ²-σ²= 0             Ha: σ²-σ²≠0

For this the critical region would be greater than the calculated value of chi square. If so we will accept the null hypothesis and reject the alternative hypothesis.

How does the graph of y= -(2x+6)^2+3 compare to the graph of a parent function
raketka [301]

Here the list of the transformations applied to the parent function, and their effect:

  1. x^2 \to (2x)^2=4x^2. This causes a horizontal compression of factor 4.
  2. (2x)^2 \to (2x+6)^2= 4(x+3)^2. This causes a horizontal translation, 3 units to the left.
  3. (2x+6)^2 \to -(2x+6)^2. This causes a reflection about the x axis.
  4. -(2x+6)^2 \to -(2x+6)^2+3. This causes a vertical translation, 3 units up

So, if you start from the graph of y=x^2, you have to compress and translate it horizontally, flip it with respect to the x axis, and finally move it up 3 units.

Volume of a Cone Formula: \displaystyle V = \frac{1}{3} \pi r^2h

  • <em>r</em> is radius
  • <em>h</em> is height

Step-by-step explanation:

<u>Step 1: Define</u>

Radius <em>r</em> = 4

Height <em>h</em> = 21

<u>Step 2: Find Volume</u>

  1. Substitute in variables [Volume of a Cone Formula]:                                      \displaystyle V = \frac{1}{3} \pi (4)^2(21)
  2. Evaluate exponents:                                                                                         \displaystyle V = \frac{1}{3} \pi (16)(21)
  3. Multiply:                                                                                                             \displaystyle V = \frac{16 \pi}{3}(21)
  4. Multiply:                                                                                                             \displaystyle V = 16 \pi \cdot 7
  5. Multiply:                                                                                                             \displaystyle V = 112 \pi

I REALLLLYYYYY NEED HELP, PLEASE?
creativ13 [48]

。☆✼★ ━━━━━━━━━━━━━━  ☾  

Use this equation:

final = original x multiplier^n

Lets calculate the multiplier

5/100 = 1.05

n is the number of years.

Substitute values in:

final = 3500 x 1.05^10

final = 5701.131194

The answer is $5701.13
