In August 2003, 56% of employed adults in the United States reported that basic mathematical skills were critical or very important to their job. The supervisor of the job placement office at a 4-year college thinks this percentage has increased due to increased use of technology in the workplace. He takes a random sample of 530 employed adults and finds that 324 of them feel that basic mathematical skills are critical or very important to their job. Is there sufficient evidence to conclude that the proportion of employed adults who feel basic mathematical skills are critical or very important to their job has increased at the α = 0.01 level of significance?

The sample proportion is p^ =______- . (Round to 3 decimal places.)
The test statistic for this test is z₀=_______. (Calculate this value in a single step in your calculator using the rounded sample proportion reported above, and report your answer rounded to 3 decimal places.)

We (reject / fail to reject) H₀.
The given data (does / does not) provide significant evidence that the proportion of employed adults who feel that basic mathematical skills are critical or very important to their job has increased since August 2003.
