Transcribed Image Text:12. In a Leichtman Research Group survey of 900 TV households, 74.9% 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 77%. Test that claim using a 0.10 significance
level. Use the P-value method. Use the normal distribution as an approximation to the binomial
distribution.
Let p denote the population proportion of all homes with at least one Internet-connected TV
device. Identify the null and alternative hypotheses.
Ho: p(1).
H1: p (2).
