---### Normal Distribution Problems Using Standardized Test Scores**Use the normal distribution to the right to answer the questions.**(a) What percent of the scores are less than 19? (b) Out of 1500 randomly selected scores, about how many would be expected to be greater than 21?**Graph Explanation:**The graph provided is a normal distribution curve labeled "Standardized Test Composite Scores." - The mean (µ) of the distribution is 19.9. - The standard deviation (σ) is 5.3.The x-axis represents the scores, with specific points marked at 19 and 21.**Questions:**(a) The percent of scores that are less than 19 is \( \boxed{\ \ \ \ } \)%. (Round to two decimal places as needed.)(b) About \( \boxed{\ \ \ \ } \) scores would be expected to be greater than 21. (Round to the nearest whole number as needed.)---

For assumed variable, the z-score for X is, And Z is assumed to follow N(0,1).

One hundred teachers attended a seminar on mathematical problem solving. The attitudes of representative sample of 12 of the teachers were measured before and after the seminar. A positive number for change in attitude indicates that a teacher's attitude toward math became more positive. The twelve change scores are as follows. 4; 7; −1; 1; 0; 5; −2; 2; −1; 6; 5; −3 Part (a) What is the mean change score? (Round your answer to two decimal places.)
A survey was conducted two years ago asking college students their top motivations for using a credit card. You think this distribution has changed. You randomly select 425 college students and ask each one what the top motivation is for using a credit card. Can you conclude that there has been a change in the distribution? Use a = 0.025. Complete parts (a) through (d). Response Old Survey % 29% New Survey Frequency, f Rewards 110 Low rates Cash back Discounts 23% 96 21% 109 7% 46 Other 20% 64 O B. The distribution of motivations is 110 rewards, 96 low rate, 109 cash back, 46 discounts, and 64 other. O C.

According to a census company. 7 1% of all bables bom are of low birth weight. An obstetrician wanted to know whether mothers between the ages of 35 and 39 years give birth to a higher percentage of low-birth-weight babies. She randomly selected 240 births for which the mother was 35 to 39 years old and found 28 low-birth-weight bables. Complete parts (a) through (c) below. (a) lf the proportion of low-birth-welght babies for mothers in this age group is 0.071, compute the expected number of low-birth-weight births to 35- to 39-year-old mothers. What is the expected number of births to mothers 35 to 39 years old that are not low birth weight? The expected number of low birth-weight births to 35- to 39-year-old mothers is The expected number of births to mothers 35 to 39 years old that are not low birth weight is (Type integers o decimals)
