which box plot best represents the data?

Use a stem-and-leaf plot to display the data, which represent the numbers of hours 24 nurses work per week. Describe any patterns. 40 40 44 48 38 40 36 50 32 36 40 35 30 26 40 36 40 36 40 33 40 32 38 29 Determine the leaves in the stem-and-leaf plot below. Key: 313 = 33 Hours worked What best describes the data? O A. Most nurses work between 40 and 50 hours per week, inclusive. O B. Most nurses work between 30 and 40 hours per week, inclusive. OC. Most nurses work over 40 hours per week. O D. Most nurses work under 40 hours per week. 0

There are 9 girls and 12 boys in the classroom. What percentage of the classroom are girls? A. 75%B. 133%C. 42.8%

This stem and leaf plot shows the height of several trees. Height in Feet and Inches of Several Trees 5 0,0,2,4,4,4,7 6 5,6 7 0,1,1,8,11 85 What is the number of trees that are LESS than 7 feet tall?

The ages (in years) and heights (in inches) of all pitchers for a baseball team are listed. Find the coefficient of variation for each of the two data sets. Then compare the results.  heights      Ages 73              28 76              22 74              23 72             24 77             24 78             27 76            31 79            28 73            27 78           35 74           33 79           36

An advertising firm has decided to ask 98 customers at each of four local shopping malls if they are willing to take part in a market research survey. At αα = 0.05 is there evidence to show that the proportions are not all the same.   A B C D Willing 69 65 68 70 Not Willing 29 33 30 28 What are the expected numbers? (round to 3 decimal places)   A B C D Willing         Not Willing         The hypotheses are    H0:pA=pB=pC=pDH0:pA=pB=pC=pD   HA:HA: At least one of the proportions is different. (claim) Since αα = 0.05 the critical value is 7.815 The test value is:  (round to 3 decimal places) The p-value is  (round to 3 decimal places) So the decision is to    do not reject H0H0 reject H0H0 Thus the final conclusion is   There is not enough evidence to support the claim that at least one of the proportions is different. There is not enough evidence to reject the claim that at least one of the proportions is different. There is enough evidence to reject the claim…
