Round 1
In a Standard Normal Distribution, find the value of each of the following.
A = (-3,3)
B = invnorm(0.6)=0.25
C =
D = Q1=invnorm(0.25)=-.6744897495; Q3=invnorm(0.75)=0.6744897495; IQR=Q3-Q1=0.6744897495- - 0.6744897495= 1.35
Round 2
A fair die is rolled. Find the probability of each as a simplified fraction:
A = (1/2)(1/2)=1/4
B = (1/2)(1/2)=1/4
C = 5/6 (all but 1 because 1 is neither prime nor composite)
D = (1/6)(1/6)=1/36
Round 3
A = SRS
B = Multi-Stage
C = Stratified
D = Systematic
Round 4
Find the value for each:
A = 12!=479001600
B = 3!3!4!5! - order of subjects x # of Stat books x # of Calc books x # of Geo books=103,680
C = (4!)(3!)(5!)=24(6)(120)=17,280
D = 7!/2!2!=1260
Round 5
Linereg(a+bx): a=11.2572 b=0.37994 r=0.355
A = Positive
B = -5.42
C = 0.36
D = y=11.3+0.4x
Round 6
A = 48%
B = 10%
C = W:234 M:250
D = 27%
Round 7
P= 15% of students at Vero Beach High School wear glasses
A = binopdf(3,0.15,3)=0.0034
B = 1-binompdf(2,.15,2)=0.9775
C = geompdf(.15,4)=0.0921
D = binopdf(3,0.85,3)=0.6141
Round 8
A = (.4)( 94)+(.35)(89)+(.25)83=89.5
B = (.4)( 85)+(.35)(x)+(.25)100=90
.35x=31;x=88.57 so an 89
C = 75
D = 10 out of 100 points is 10%, 10% of 35% of their grade is 3.5% of their grade.
Round 9
A = Matched Pairs
B = Two Sample
C = Two-Sample
D = Matched Pairs
Round 10
A = M
B = M
C = Neither
D = I
Round 11
20 students are in Mrs. Hillard’s First Period Class. 12 of her students play Football. 5 of her students are in band. All of her students are on Math Team. 2 of her band students play Football. 6 of her students are on Masterminds team. 2 of her Masterminds students are also in Band.
A = 4
B = 5
C = 2/5=40%
D = 15/20=75%
Round 12
Miami / San Diego / TotalOn Time / 402 / 295 / 697
Early / 73 / 47 / 120
Late / 80 / 103 / 183
Total / 555 / 445 / 1000
A = 183/1000
B = 73/1000
C = 295/697
D = 80/555=16/111
Round 13
A = Right-skewed (concentration of frequency to the left)
B = 190 (188ish)
C = 20 (202-180=22ish)
D = 170 (172ish)
