Assume that we want to construct a confidence interval. Do one of the​ following, as​ appropriate:_________.
andreyandreev [35.5K]

Answer:

B. z Subscript alpha divided by 2 zα/2 = 1.96.

Step-by-step explanation:

We are given that we want to construct a confidence interval. For this, the summary statistics for randomly selected weights of newborn​ girls:

n = 236​, \bar x = 30.3 ​hg, s = 7.2 hg. The confidence level is 95​%.

As we can clearly see here that the population standard deviation is unknown and the sample size is also very large.

It has been stated that when the population standard deviation is unknown, we should use t-distribution but since the sample size is very large so we can use z distribution also as it is stated that at very large samples; the t-distribution corresponds to the z-distribution.

Here, \alpha = level of significance = 1 - 0.95 = 0.05 or 5%

         \frac{\alpha}{2}=\frac{0.05}{2} = 0.025 or 2.5%

So, the value of Z_(_\frac{\alpha}{2} _) in the z table is given as 1.96 with a 2.5% level of significance.

Write in slope-intercept form an equation of the line that passes through the given points. (-16,8), (-4,5)
sergey [27]

Answer:

y=-1/4x+4

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(5-8)/(-4-(-16))

m=-3/(-4+16)

m=-3/12

m=-1/4

y-y1=m(x-x1)

y-8=-1/4(x-(-16))

y-8=-1/4(x+16)

y-8=-1/4x-16/4

y-8=-1/4x-4

y=-1/4x-4+8

y=-1/4x+4
