Amanufacturer claims that 40% of households are planning to purchase a new television in the next two years. an investment analyst is skeptical of this claim. in a survey of 1,010 randomly selected american households, only 374 responded that they plan to purchase a tv in the next two years. is there convincing evidence that less than 40% of u. s. households plan to purchase a tv? what are the appropriate hypotheses for this test?
