At a middle school campus, the number of text messages sent by males and females were analyzed. Twelve random female students and 12 random male students were asked how many text messages they sent that day. The following data was calculated from the number of text messages sent during the day for males and females.    Females   MalesMean 112 99Median 68 52Mode 78 78Range 84 76Based on these samples, what generalization can be made? A. Males sent more total text messages than females. B. A female sent the most number of text messages out of both groups. C. The modes of text messages sent by both males and females are the same. D. Not enough information is provided to draw any of these conclusions.Reset Next

A study of a local high school tried to determine the mean number of text messages that each student sent per day. The study surveyed a random sample of 96 students in the high school and found a mean of 165 messages sent per day with a standard deviation of 52 messages. At the 95% confidence level, find the margin of error for the mean, rounding to the nearest whole number.

4) In a survey looking at the mobile phone usage habits of university students, the following question was asked..

Four to eight text messages IV. More than eight text messages" The data from this survey should be regarded as including: A. Categorical variables measured on a nominal scale B. Quantitative variables measured on an interval scale C. A discrete variable measured on an ordinal scale D. Numerical variables measured on a ratio scale

A professor wanted to know more about media consumption habits among the students in his class. He took note of each student's gender ("Male" or "Female") and asked the student which communication platform they used most often (either "Telegram" or "Whatsapp"). It was found thatrate(Male | Telegram) > rate(Male | Whatsapp). Which of the following statements must be true?(I)  rate(Telegram | Male) > rate(Telegram | Female).(II) rate(Female | Telegram) < rate(Female | Whatsapp).(III) rate(Whatsapp | Female) < rate(Whatsapp | Male).

A group of teenagers want to know how fast, on average, they can type text messages.  The students each type the same text message and record their times. What type of study is ddscribed?

A study of a local high school tried to determine the mean number of text messages that each student sent per day.  The study surveyed a random sample of 30 students in the high school and found a mean of 181 messages sent per day with a standard deviation of 70 messages.  At the 95% confidence level, find the margin of error for the mean, rounding to the nearest whole number.  Margin of Error = 2(sn√)2(𝑠𝑛)where s is the standard deviation and n is the sample size.
