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
A) Slope = 5, for the y intercept plug 0 into x, so y=5(0)+10 =10. So the y-intercept is (0,10)
c) I added the graph below. First you plot the y intercept, (0,10). Then count 5 up and 1 right and plot a point because the slope is (5/1) "slope is easy and fun, rise over run." You can go the opposite way too, 5 down and 1 left and then plot a point. Plot 5-7 points. The x-axis is time, because that is the independent variable and the y-axis is baskets of berries because that is the dependent variable.
