A decade-old study found that the proportion of high school seniors who felt that "getting rich" was an important personal goal

juin [17]

Answer: $H_0:p\leq0.72$

$H_a:p\neq0.72$

Step-by-step explanation:

Given : A decade-old study found that the proportion of high school seniors who felt that "getting rich" was an important personal goal was 72% .

Let 'p' be the new proportion of high school seniors who felt that "getting rich" was an important personal goal .

Claim : $p\neq0.72$

We know that the null hypothesis has equal sign.

Therefore , the null hypothesis for the given situation will be opposite to the given claim will be :-

$H_0:p=0.72$

And the alternative hypothesis must be :-

$H_a:p\neq0.72$

Hence, the null hypothesis and the alternative hypothesis that we would use for this test :

$H_0:p\leq0.72$

$H_a:p\neq0.72$

Stells [14]

Answer: $\dfrac14$

Step-by-step explanation:

Given: The factory produces equal quantities of four flavors cherry lemon orange and strawberry.

Let orange candy= cherry = lemon = strawberry = x

Total candies = x + x + x + x= 4x

The probability that a randomly selected candy is orange = $\dfrac{x}{4x}=\dfrac14$

Hence, the probability that a randomly selected candy is orange = $\dfrac14$
