An education firm measures the high school dropout rate as the percentage of 16 to 24 year olds who are not enrolled in school a
posledela

Answer:

The value of the test statistic z = -0.6606

Step-by-step explanation:

From the question we are told that

      The high dropout rate is \mu  = 6.1%  = 0.061

      The  sample size is  n = 1000

       The  number of dropouts x = 56

       The probability of having a dropout in 1000 people  \= x  = \frac{56}{1000}  =  0.056

Now setting up Test Hypothesis

 Null  H_o :  p = 0.061

 Alternative  H_a : p < 0.061        

The Test statistics is mathematically represented as

                 z = \frac{\= x - p}{\sqrt{\frac{p(1 -p)}{n} } }

substituting values

               z = \frac{0.056 - 0.061}{\sqrt{\frac{0.061(1 -0.061)}{1000} } }

               z = -0.6606

What is the answer to 5v-4/10=4/5
Tatiana [17]

Answer:

v = 6/25

Step-by-step explanation:

Given that:

5v-4/10=4/5

Simplifying by reducing 4/10 to 2/5 (Dividing both by 2)

5v-2/5=4/5

  • Add 2/5 on both sides:

5v - 2/5 + 2/5 = 4/5 +  2/5

5v = (4 + 2)/5                 (As denominators are same)

5v = 6/5

Dividing both sides by 5 we get:

v = 6/(5*5)

v = 6/25                         required answer

I hope it will help you!
