Find the (a) mean, (b) median (c) mode: and (d) midrange for the given sample data. An experiment was conducted to determine whether a deciency of carbon dioxide in the soil aftects the phenotype of peas. Listed below are the phenotype codes where 1 : smoothyellow: 2 : smoothgreen 3 : wrinkled-yellow: and 4 : wrinkled-green Do the results make sense? 4 2 2 t 3 4 2 2 1 4 2 4 t 2 D (a) The mean phenotype code is (Round to the nearest tenth as needed.) (h) The median phenotype code is (Type an integer or a decrmal) (c) Select the correct choice below and fill in any answer boxes Within your choice. C' A- The mode phenotype code is (Use a comma to separate answers as needed.) {3' B. There is no mode (d) The midrange of the phenotype codes is (Type an integer or a decimal) Do the measures of center make sense? {j A. Only the mean: median: and midrange make sense Since the data is nominal Only the mode makes sense since the data is nominal. Only the mean. median. and mode make sense Since the data is numerical. . All the measures of center make sense since the data is numerical. Assume that the amounts of weight that male college students gain during their freshman year are normally distributed with a mean of u = 1.3 kg and a standard deviation of o = 4.4 kg. Complete parts (a) through (c) below. . . . a. If 1 male college student is randomly selected, find the probability that he gains between 0 kg and 3 kg during freshman year. The probability is (Round to four decimal places as needed.) b. If 4 male college students are randomly selected, find the probability that their mean weight gain during freshman year is between 0 kg and 3 kg. The probability is. (Round to four decimal places as needed.) c. Why can the normal distribution be used in part (b), even though the sample size does not exceed 30? O A. Since the original population has a normal distribution, the distribution of sample means is a normal distribution for any sample size. O B. Since the weight gain exceeds 30, the distribution of sample means is a normal distribution for any sample size. O C. Since the distribution is of individuals, not sample means, the distribution is a normal distribution for any sample size. O D. Since the distribution is of sample means, not individuals, the distribution is a normal distribution for any sample size
