Test the claim that the proportion of people who own cats is significantly different than 90% at the 0.1 significance level.

Mathematics
1 answer:
miss Akunina [59]3 years ago
4 0

Answer:

The right answer is Option B:

H_0: \pi=0.9\\\\H_1: \pi\neq0.9

Step-by-step explanation:

In this case we have to perform a hypothesis test on the proportion of the people owning cats.

The claim is that the proportion is significantly different than 905, what means it can be greater or smaller than 90% to reject the null hypothesis. Because of that, the null hypothesis has to state an equality (H0:p=0.9).

The right answer is Option B:

H_0: \pi=0.9\\\\H_1: \pi\neq0.9

The cost of John’s bike(p) cannot exceed $5,000. Write this sentence in the form of a set notation.
lakkis [162]

Answer:

p = \{x \ |  \ x \in Q^+ \  and \ x \leq \$5,000 \}

Step-by-step explanation:

The expression for the cost of John's bike (p) using set notation can written as follows;

We note that the cost of the bike is a member of the positive rational number  and the cost price of the bike cannot exceed $5,000, therefore, it is less than or equal to $5,000, therefore, we get the following set notation;

p = \{x \ |  \ x \in Q^+ \  and \ x \leq \$5,000 \}
