A research center claims that 30% of adults in a certain country would travel into space on a commercial flight if they could afford it. In a random sample of 1100 adults in that country, 33% say that they would travel into space on a commercial flight if they could afford it.

A research center claims that 30% of adults in a certain country would travel into space on a commercial flight if they could afford it. In a random sample of 1100
adults in that country, 33% say that they would travel into space on a commercial flight if they could afford it. At o = 0.05, is there enough evidence to reject the
research center's claim? Complete parts (a) through (d) below.
(Round to two decimal places as needed.)
O A. Ho: p>
B. Ho:p = 0.05
C. Ho: p+
Ha: ps
Ha: p 0.05
Ha:p=
O D. Ho: p2
O E. Ho: ps
O F. Ho: p<
Ha:p<
Ha:p>
Ha: p2
(b) Use technology to find the P-value.
Identify the standardized test statistic.
z= 1.22
(Round to two decimal places as needed.)
Identify the P-value.
P =0.44
(Round to three decimal places as needed.)
(c) Decide whether to reject or fail to reject the null hypothesis and (d) interpret the decision in the context of the original claim.
Reject
the null hypothesis. There is not enough evidence to support the research center's claim.
