Two researchers, Jaime and Maria, each construct confidence intervals for the proportion of a population who is left-handed. The

tekilochka [14]

Answer:

Step-by-step explanation:

From data give above we have

Point estimate $= \hat{p} = 0.13$

Jamie interval = (0.097 , 0.163)

Mariya's interval = (0.117,0.173)

Mean value of jamie interval $= \frac{0.097+0.163}{2} = 0.13$

therefore we can say jamie interval is equal to point estimate which is equal to 0.13

Now mean of Mariyah

$\frac{0.117+0.173}{2} = 0.145$

According to the given calculation, Mariyah interval is wrong due to mean value.

Plzzzzzzzzzzzzzzzzzz need help

vlada-n [284]

Answer: A

Step-by-step explanation:

$4x+4y=20$

We need to get this form: $y=mx+b$

we need to begin by isolating y on the left side. To do this, we must subtract 4x.

$4y=20-4x$

Rewrite it so that we get this form: $y=mx+b$

$4y=-4x+20$

Since y needs to be completely isolated, divide by 4.

$y=-\frac{4x}{4} +\frac{20}{5}$

Divide;

$y=-x+5$

If m2 3 = 9n and m24 = 24n+15, then what is the value of n?

Nataly_w [17]

Answer:

n = 5

Step-by-step explanation:

$\because m \angle \: 3 + m \angle \: 4 = 180 \degree..(supplementary \: \angle s) \\ \therefore \: 9n + 24n + 15 = 180 \\ \therefore \: 33n = 180 - 15 \\ \therefore \: 33n = 165 \\ n = \frac{165}{33} \\ \huge \red{ \boxed{\therefore \: n = 5}}$
