The null and alternative hypotheses are given. Determine whether the hypothesis test is​ left-tailed, right-tailed, or​ two-tail
aleksandrvk [35]

Answer: The hypothesis test is left-tailed test.

The parameter tested here is population mean.

Step-by-step explanation:

Given : The null and alternative hypotheses are as follows:

H_0:\mu=6

H_1:\mu

We can see that the parameter tested here is population mean.

Also, the type of test depends on the alternative hypothesis.

Since the alternative hypothesis is left-tailed so the hypothesis test is left-tailed test.

TEA [102]

Answer:

The value of x will be:

  • x=-5

Step-by-step explanation:

Given the equation

4-2(x+7)=3(x+5)

Multiply (or distribute) each term in parenthesis on L.H.S by -2, and multiply (or distribute) each term in parenthesis on R.H.S by 3.

4-2x-14=3x+15

simplifying the equation by subtracting 14 from the L.H.S

-10-2x=3x+15

Subtracting 15 from both sides

-10-2x-15=3x+15-15

-25-2x=3x

combining the like terms

-25=3x+2x

-25=5x

dividing both sides of the equation by 5

\frac{-25}{5}\:=\:\frac{5x}{5}

-5=x

Therefore, the value of x will be:

  • x=-5
