Short-term classes: Does taking a class in a short-term format (8 weeks instead of 16 weeks) increase a student’s likelihood of
passing the course? For a particular course, the pass rate for the 16-week format is 59%. A team of faculty examine student data from 40 randomly selected accelerated classes and determine that the pass rate is 78%. Which of the following are the appropriate null and alternative hypotheses for this research question? a.H0: p = 0.59; Ha: p ≠ 0.59
b.H0: p = 0.59; Ha: p > 0.59
c.H0: p = 0.78; Ha: p ≠ 0.78
d.H0: p = 0.78; Ha: p > 0.59
Given that For a particular course, the pass rate for the 16-week format is 59%. A team of faculty examine student data from 40 randomly selected accelerated classes and determine that the pass rate is 78%.
we have to find whether taking a class in a short-term format (8 weeks instead of 16 weeks) increase a student’s likelihood of passing the course
Since pass rate for 16 weeks is 59% we check whether for 8 weeks is more than this.
So correct null and alternative hypotheses for this research question
X=side length of a campsite 12x(5+x)=1248 because each campsite has a length of x and there are 12 and from the top of the camp to the water is the 5 yds + a side length and LW=1248 60x+12x^2=1248 12x^2+60x-1248=0 x^2+5-14=0 (x+7)(x-2)=0 x+7=0 or x-2=0 x=-7 or x=2 x=2 because width can't be negative the width of one campsite is 2 yds
