One sample tests for proportions

A newspaper report claims that 30%30\% of all tea-drinkers prefer green tea to black tea. Leo is the office manager at a company with thousands of employees, and he wonders if the newspaper’s claim holds true at his company. To find out, Leo asks a simple random sample of 125125 tea-drinking employees which they prefer: green tea or black tea. Leo wants to perform a test of
Ho:p=0.30H_o:p=0.30
Ha:p0.30H_a: p \neq0.30
where pp is the true proportion of tea-drinking employees at Leo’s company who prefer green tea to black tea.
Suppose twenty-seven of the 125125 employees surveyed say that they prefer green tea, and this results in a pp-value of 0.040.04 for this test.
What conclusion should Leo make at the α=0.05\alpha=0.05 significance level?
