Y = 2x is the relationship since y is always double x!
eg. when x = 2, y = 4 and when x = -3, y = -6

Y=x is the answer alone, since it only crosses the origin

Answer:

$\mu_{p}=p=0.81$

Step-by-step explanation:

A confidence interval is "a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population means lies between an upper and lower interval".

The margin of error is the range of values below and above the sample statistic in a confidence interval.

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The population proportion have the following distribution

$p \sim N(p,\sqrt{\frac{p(1-p)}{n}})$

So under the null hypothesis the mean for the population proportion is p

$\mu_{p}=p=0.81$

And the standard deviationis given by:

$\sigma_{p}=\sqrt{\frac{p_0(1-p_o)}{n}}=\sqrt{\frac{0.81(1-0.81)}{1000}}=0.0124$

Tatiana [17]

Answer:

I don't think that there is two same results. sorry I couldn't help

Step-by-step explanation:

for I the answer should be 10 if you replaced each x by 2. f(2) = 3(2) + 4

and for II it will be f-1(4) = 3-1(4) - 4 /5 the answer will be -1.

for III it should be y = 8 or 4
