According to one poll, 54% of households in a certain region had no landline and only had cell phone service. Suppose a random sample of 50 households from the region is taken. Complete parts (a) through (d) below. a. Find the probability that exactly 25 of the households sampled only have cell phone service. The probability that exactly 25 only have cell phone service is 0.096. (Type an integer or a decimal. Round to three decimal places as needed.) b. Find the probability that fewer than 25 households only have cell phone service. The probability that fewer than 25 only have cell phone service is 0.239 (Type an integer or a decimal. Round to three decimal places as needed.) c. Find the probability that at most 25 households only have cell phone service. The probability that at most 25 only have cell phone service is 0.334. (Type an integer or a decimal. Round to three decimal places as needed.) d. Find the probability that between 25 and 30 households, inclusive, only have cell phone service. The probability that between 25 and 30 households, inclusive, only have cell phone service is (Type an integer or a decimal. Round to three decimal places as needed.)

Please do not give solution in image format thanku Newborn babies are more likely to be boys than girls. A random sample found 13,173 boys were born among 25,468 newborn children. The sample proportion of boys was 0.5172. Is this sample evidence that the birth of boys is more common than the birth of girls in the entire population?
Describe about the interpret decision in terms of the original research problem.

Please teach me on how to solve this problem. C is wrong, maybe B, because it's talking about "sample ", and definitely "36students " are just samples, not population. Thanks so much.
