Answer:
a) Critical value = -1.285
b) We should reject null hypothesis that the mean equals 0.32
Step-by-step explanation:
Given that the statistic of z equals negative 2.40 is obtained when testing the claim that less than 0.32
i.e. for hypotheses
(one tailed test at 10% significance level)
Z critical value for 90% one tailed = -1.285
Since our test statistic is less than -1.285 we reject null hypothesis
a) Critical value = -1.285
b) We should reject null hypothesis that the mean equals 0.32
Use Desmos, you can type in any equation (such as this one) and it’ll form a graph for you desmos.com/calculator
Answer:
The equation would be y = 3/2x - 1
Step-by-step explanation:
To find the answer in slope-intercept form, simply solve for y.
4x-4y/2=x+2 ----> Subtract 4x from both sides
-4y/2=-3x+2 ----> Multiply both sides by 2
-4y = -6x + 4 -----> Divide by -4
y = 3/2x - 1
