Best ResponseYou've already chosen the best response.0The price of some houses in a neighborhood are shown below: House Price A $120,000 B $130,000 C $140,000 D $150,000 E $1,110,000 Based on the data, should the mean or the median be used to make an inference about the price of the houses in the neighborhood? Median, because there is an outlier that affects the mean Mean, because there are no outliers that affect the mean Median, because it is in the center of the data Mean, because it is in the center of the data

Best ResponseYou've already chosen the best response.0Jack wants to know how many families in his small neighborhood of 60 homes would help organize a neighborhood fundraising party. He put all the addresses in a bag and drew a random sample of 30 addresses. He then asked those families if they would help organize the fundraising party. He found that 12% of the families would help organize the party. He claims that 12% of the neighborhood families would be expected to help organize the party. Is this a valid inference? No, this is not a valid inference because he asked only 30 families No, this is not a valid inference because he did not take a random sample of the neighborhood Yes, this is a valid inference because he took a random sample of the neighborhood Yes, this is a valid inference because the 30 families speak for the whole neighborhood

Best ResponseYou've already chosen the best response.0I will say look at 35 hours, and the sample is from 100 students, and we have 62 students who play at least 3  5 hours a day. So that's 62%, just multiply 1200 by 62%.

Best ResponseYou've already chosen the best response.0now we have to write that proportion for a sample of 1200 students, so the requested number of students, which play outdorr games, for a sample of 1200 students, is: \[\Large \frac{{62}}{{100}} \cdot 1200 = ...?\]
