Help please...<br> Which graph represents a proportional relationship?

nlexa [21]

Answer:

Graph C.

Step-by-step explanation:

The graph which illustrates a proportional relationship is graph c because as the value on the Y-axis increases, the values on the X-axis increases consequently.

A direct proportion implies that the values of the quantities on both sides are increasing at a constant rate. Critically looking at graph c, you will notice or observe that the values both intersect at specific intervals or points on the graph.

A 95% confidence interval for a population mean is (28, 35). Using the same data at 5% level of significance, what should you de

iris [78.8K]

Answer:

A) Fail to reject the null hypothesis because 34 falls in the 95% confidence interval.

Step-by-step explanation:

We are given the following information in the question:

A 95% confidence interval for a population mean is (28, 35)

Alpha, α = 0.05

The null and the alternate hypothesis are:

$H_{0}: \mu = 34\\H_A: \mu \neq 34$

A confidence interval also known as the acceptance region, is a set of values for the test statistic for which the null hypothesis is accepted.
If the observed test statistic lies in the confidence interval then we accept the null hypothesis and reject the alternative hypothesis.
If the observed test statistic is in the critical region then we reject the null hypothesis and accept the alternative hypothesis.

Hence, we fail to reject the null hypothesis and accept it because 34 falls in the 95% confidence interval.

Vlad1618 [11]

(2/5) of (2/3) of students = 4/15 of students study French. Then 1-(4/15) = 11/15 of students do not study French. The ratio you want is
(4/15):(11/15) = 4:11
