The answer is B ..................
Answer:
<u>y=5x-7</u>
Step-by-step explanation:
1. First the slope: -17-8/-2-3= -25/-5=5
2. What is your line equation now? y=5x+b
3. Replace the x and y value with one of the coordinate points: 8=5(3)+b
4. Solve for b: 8=15+b -7=b
5. Substitute it in the equation: y=5x-7
Hope this helps!
Answer: 2.5
Step-by-step explanation:
Answer:
we will fail to reject the null hypothesis and conclude that there's insufficient evidence to support the claim that the percentage is actually more than the reported percentage
Step-by-step explanation:
We are given;
Population proportion; p = 30% = 0.3
Sample proportion; p^ = 37% = 0.37
Sample size; n = 100
Let's define the hypotheses;
Null hypothesis; H0: p ≤ 0.3
Alternative hypothesis; Ha: p > 0.3
Formula for the test statistic is;
z = (p^ - p)/√(p(1 - p)/n)
Thus;
z = (0.37 - 0.3)/√(0.3(1 - 0.3)/100)
z = 0.07/0.04582575695
z = 1.53
From z-distribution table, at z=1.53 we have;
p-value = 1 - 0.9370 = 0.063
This p-value is greater than the significance level of 0.02 and thus we will fail to reject the null hypothesis and conclude that there's insufficient evidence to support the claim that the percentage is actually more than the reported percentage
