Question

5. A recent survey found that 68.8% of the population own their homes. In a random sample of 150 heads of households, 92 responded that they owned their homes. At the $\alpha$=0.01 level of significance, does that suggest a difference from the national proportion? 6. A survey by Men's Health magazine stated that 14% of men said they used exercise to reduce stress. Use $\alpha$=0.10. A random sample of 100 mean was selected, and 10 said that they used exercise to relieve stress. Use the P-value method to test the claim. Could the results of be generalized to all adult Americans?
