Suppose a large bucket contains a population of thousands of sunflower seeds. From the bucket, a simple random sample of 50 seeds is collected, and exactly 44 of the seeds germinate.

For a 95% confidence interval, what is the value of n, ρˆ , and zcrit ?

n=50, ρˆ=44, zcrit=1.64

n=44, ρˆ=88, zcrit=1.96

n=50, ρˆ=88, zcrit=1.96

n=44, ρˆ=88, zcrit=1.64

Given the system of equations presented here: 2x + 4y = 14 4x + y = 20 which of the following actions creates an equivalent system such that, when combined with the other equation, one of the variables is eliminated? multiply the second equation by â’4 to get â’16x â’ 4y = â’80 multiply the second equation by â’1 to get â’4x â’ y = â’20 multiply the first equation by 2 to get 4x + 8y = 28 multiply the first equation by â’1 to get â’2x â’ 4y = â’14
