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

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

$z = -0.6606$

A salsa recipe uses green pepper, and onion, and tomato in the extended ratio 2:5:9. How many cups of onion are needed to make 9

Vlad1618 [11]

The answer is 30 cups

Let x be a multiplier. So:
2x + 5x + 9x = 96
16x = 96
x = 96/16
x = 6 cups

Since the number of onion cups is 5x, then 5 * 6 = 30 cups are needed to make 96 cups of salsa.
