In a Leichtman Research Group survey of 1150TV households, 75% 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

0.05

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.
