The mean annual tuition and fees for a sample of 12 private colleges was 36,800 with a standard deviation of 5,000 . A dotplot s
Ilya [14]

Answer:

The value of the test statistic and degrees of freedom is 2.148 and 11 respectively.

Step-by-step explanation:

Consider the provided information.

The mean annual tuition and fees for a sample of 12 private colleges was 36,800 with a standard deviation of 5,000 .

Thus, n = 12, \bar x=36800 σ = 5000

degrees of freedom = n-1 = 12-1 = 11

H_0: \mu = 33700\ and\ H_a: \mu \neq 33700

Formula to find the value of z is: z=\frac{\bar x-\mu}{\frac{\sigma}{\sqrt{n}}}

Where \bar x is mean of sample, μ is the mean of population, σ is the standard deviation of population and n is number of observations.

z=\frac{36800-33700}{\frac{5000}{\sqrt{12}}}

z=2.148

Hence, the value of the test statistic and degrees of freedom is 2.148 and 11 respectively.

−7m+4&lt;−45 <br><br> its an one-step problem help me please
aleksandr82 [10.1K]

Answer:

x > 7

Step-by-step explanation:

- 7m + 4 < - 45 ( subtract 4 from both sides )

- 7m < - 49

Divide both sides by - 7 , reversing the symbol as a result of dividing by a negative quantity.

m > 7
