Question

A research center claims that

29%

of adults in a certain country would travel into space on a commercial flight if they could afford it. In a random sample of

1000

adults in that country,

33%

say that they would travel into space on a commercial flight if they could afford it. At

α=0.10,

is there enough evidence to reject the research center's claim?

(a) Identify the claim and state

and

Ha.

Identify the claim in this scenario. Select the correct choice below and fill in the answer box to complete your choice.

(Type an integer or a decimal. Do not round.)

No more than

nothing%

of adults in the country would travel into space on a commercial flight if they could afford it.
