. Test that claim using a .01 significance level. Use the P-value method. Use the normal distribution as an approximation to the binomial distribution. a. Let p denote the population proportion of all homes with at least one Internet-connected TV device. Identify the null and alternative hypotheses. H0:p? H1:p? b. Identify the test statistic. z=? c.Identify the P-value. p-value=
In a Leichtman Research Group survey of 1100 TV households, 75.1% of them had at least one Internet-connected TV device (for example, Smart TV, standalone streaming device, connected video game console). A marketing executive wants to convey high penetration of Internet-connected TV devices, so he makes the claim that the percentage of all homes with at least one Internet-connected TV device is equal to 78%. Test that claim using a .01 significance level. Use the P-value method. Use the normal distribution as an approximation to the binomial distribution.
