2. Which is a continuous random variable? O w = "number of apps on your phone" O x = "number of petals on a sunflower" %D O z = "results of drawing three cards from a standard deck of cards" O Y = "exact age of your classmates"

Stress at work: In a poll about work,  51%  of respondents said that their jobs were sometimes or always stressful. Eleven workers are chosen at random.What is the mean number who find their jobs stressful in a sample of  11  workers? Round the answer to two decimal places.

Give the percent of scores between the mean and the z-value of normally distributed random variable. a 1) 1.25

The accompanying table describes results from groups of 8 births from 8 different sets of parents. The random variable x represents the number of girls among 8 children. Complete parts (a) through (d) below. Click the icon to view the table. a. Find the probability of getting exactly 1 girl in 8 births. (Type an integer or a decimal. Do not round.) b. Find the probability of getting 1 or fewer girls in 8 births. (Type an integer or a decimal. Do not round.) c. Which probability is relevant for determining whether 1 is a significantly low number of girls in 8 births: the result from part (a) or part (b)? *** O A. Since getting 0 girls is an even lower number of girls than getting 1 girl, the result from part (b) is the relevant probability. OB. Since the probability of getting 0 girls is less likely than getting 1 girl, the result from part (a) is the relevant probability. OC. Since the probability of getting more than 1 girl is the complement of the result from part (b), this is the…
