The mean annual tuition and fees for a sample of 14 private colleges in California was $37,900 with a standard deviation of $7,2

JulijaS [17]

Answer:

Z_{0.005}>Z H₀ is wrong and other is correct. IT means $35000 is not mean value.

Step-by-step explanation:

Two hypothesis:

H₀=$35,000

Hₐ≠$35,000

Test Formula:

$Z=\frac{(X-u)}{\frac{S}{\sqrt{n} } }$

Where:

X is the mean value=$37,900

u is the value with 0.01 significance=$35000

S is the standard deviation

n is the sample size

$Z=\frac{(37900-35000)}{\frac{7200}{\sqrt{14} } }$

Z=1.507

Z with 0.01 significance:

0.01/2=0.005=0.05%

Degrees of freedom=14-1=13

From t distribution table at 0.05% and 13 dof:

$Z_{0.005}$ =4.221

Z_{0.005}>Z H₀ is wrong and other is correct. IT means $35000 is not mean value.

Andre is solving the inequality 14x+3 is less than or equal to 8x+3.he first solves a related equation

Arte-miy333 [17]

Answer:

14x+3=8x+3

14x+3 -3 = 8x+3 -3

Cancels out the 3

14x = 8x

14x - 8x = 8x -8x

Cancels out the 8x

14x = 0

x = 0

Drag each expression to show whether the product is less than 1

barxatty [35]

Equal to 1:

$3*\frac{1}{3}\ \ , \ \ 5*\frac{1}{5}\ \ , \ \6*\frac{1}{6}$

Less than 1:

$1*\frac{5}{6}$

Greater than 1:

$2 * \frac{3}{4} \ \ , \ \ \ 3 * \frac{2}{5}$

Step-by-step explanation:

We will solve each product one by one.

So,

$3*\frac{1}{3} = 1\\\\6*\frac{1}{6} = 1\\\\2 * \frac{3}{4} = \frac{3}{2}\\\\1*\frac{5}{6} = \frac{5}{6}\\\\3*\frac{2}{5} = \frac{6}{5}\\\\5*\frac{1}{5} = \frac{1}{5}$

As we have all the answers now.

If the denominator of a fraction is greater than ts numerator then the result is less than 1
If the denominator of a fraction is less than its numerator then the result is greater than 1.

So,

Equal to 1:

$3*\frac{1}{3}\ \ , \ \ 5*\frac{1}{5}\ \ , \ \6*\frac{1}{6}$

Less than 1:

$1*\frac{5}{6}$

Greater than 1:

$2 * \frac{3}{4} \ \ , \ \ \ 3 * \frac{2}{5}$
