A marketing survey is conducted in which students are to taste two different brands of soft drink.Their task is to correctly identify the brand tasted.A random sample of 200 students is taken.Assume that the students have no ability to distinguish between the two brands. b.The probability is 90%that the sample percentage is contained within what symmetrical limits of the population percentage?Identify the limits of the population percentage. The lower limit is The upper limit is (Round to four decimal places as needed.)

A new soft drink is being market tested. A sample of 400 individuals participated in the taste test and 80 indicated they like the taste. At a 5% significance level, test to determine if at least 22% of the population will like the new soft drink.What is the test statistic? Group of answer choices-.97-.74.79.47

Suppose your friends have the following ice cream flavor preferences:70% of your friends like Chocolate (C). The remaining do not like Chocolate.40% of your friends like Sprinkles (S) topping. The remaining do not like Sprinkles.25% of your friends who like Chocolate (C) also like Sprinkles (S).Of the friends who like Chocolate, which of the following probabilities do you need to find in order to determine the proportion of friends who like Chocolate that also like Sprinkles? P(C) P(S) P(C and S) P(C | S) P(S | C)Question 2Select one answer.10 pointsSuppose your friends have the following ice cream flavor preferences:70% of your friends like chocolate (C). The remaining do not like chocolate.40% of your friends like sprinkles (S) topping. The remaining do not like sprinkles.25% of your friends who like Chocolate (C) also like sprinkles (S).Of the friends who like sprinkles, what proportion of this group likes chocolate?

Denote this by H (the remaining were away games).Of all the games, 25% owere wins. Denote this by W (the remaining were losses).Of all the games, 20% were at-home wins.If the team won a game, how likely is it that this was a home game?

A 1992 study of Dalmatians (by Strain and others, as reported in The Dalmatians Dilemma) found the following:(i) 31% of all Dalmatians have blue eyes.(ii) 38% of all Dalmatians are deaf.(iii) If a Dalmatian has blue eyes, there is a 42% chance that it is deaf.Based on the results of this study is "having blue eyes" independent of "being deaf"? No, since 0.38 is not equal to 0.42. Yes, since 0.31 * 0.38 is not equal to 0.42. Yes, since 0.38 is not equal to 0.42. No, since 0.31 is not equal to 0.42.
