I think the easiest way is to get a common denominator. So I will show you that way. (another way is to change it from fractions to decimals).
So at first we have:
2/5 5/8 57/100
(57/100 comes from 0.57, since it is in the hundredths place you put it over 100)
The Least Common Multiple between 5, 8, and 100 is 200
2/5 = 2x40 and 5x40 = 80/200
5/8 = 5x25 and 8x25 = 125/200
57/100 = 57x2 and 100x2 = 114/200
So the answer would be: Sunday, Wednesday, Monday
3.because I found it. hahaha
Answer and explanation:
Null hypothesis(H0) says sentiment for increasing speed limit in the two populations is the same
Alternative hypothesis(Ha) says sentiment for increasing speed limit in the two populations is different
Where p1 is the first population proportion =65/297= 0.22
And p2 is the second population proportion = 78/189= 0.41
P= p1+p2/n1+n2= 65+78/297+189= 0.29
Hence H0= p1-p2=0
Ha=p1-p2≠0
Test statistic= p1-p2/√p(1-p) (1/n1+1/n2)
= 0.22-0.41/√0.29(1-0.29)(1/297+1/189)
= -4.49
Critical value at 95% significance level= 1.96( from tables)
We therefore reject null hypothesis as critical value is greater than test statistic
Therefore the sentiment for increasing speed limit in the two populations is different
b. at proportions of 0.24 and 0.40 for p1 and p2 respectively
Test statistic = 0.24-0.40/0.29(1-0.29)(1/297+1/189)
= -3.78
P value is 0.0002 at 0.05 significance level
Hence probability =0.4998
17113 divided by 100=171.13
171.13*10=1711.3
17113+1711.3=18824.3
You can then round this to get a whole number if you need to.
Hope I helped xx
