Answer #1

X : number of days absent

X ~ N( 3.2, 1.2)

where, mean () = 3.2

and sd () = 1.2

the probability that a particular student missed between 3.5 and 5 days be:-

[ from standard normal table]

= 0.3345

    4. A college counselor claims that there is a negative correlation between the number of days a student was absent from class and the student’s score on the midterm examination. A random sample of 30 statistics students was examined. The sample correlation coefficient was computed to be r = -0.67. Assuming that both the attendance and the midterm grades are normally distributed, is the counselor’s claim justified at the 1% level of significance? Explain your answer.
