A recent survey done by the Philippine Housing Authority found that 35% of the population owns their homes. In a random sample of 240 heads of households, 78 responded that they owned their homes. At the 0,01 level of significance, that that indicate a difference from the national proportion? Solution: Given: x=78 p 35%= 0.35 Step 1: Formulate the null and alternative hypotheses fam of noiffy Ho: The proportion of the population, who owns their homes is 0.35.

To test this claim, a researcher surveyed 200 professors and found that 45 had attended a national convention in the past year. At a=0.05, test the claim.
