According to the Centers for Disease Control and Prevention (February 18, 2016), 1 in 3 American adults don’t get enough sleep.
Marizza181 [45]

Answer:

A) Option C: H0: μ ≥ 7; HA: μ < 7

B) test statistic = -1.75

C) Option C: 0.025 ≤ p-value < 0.05

D) Option C: Do not reject H0 since the p-value is greater than α.

E) Option A: There is insufficient evidence to suggest that Americans sleep less than the recommended 7 hours of sleep.

Step-by-step explanation:

We are given;

Population mean; μ = 7

Sample mean; x = 6.7

Standard deviation; s = 2.1

Sample size; n = 150

A) Defining the hypothesis, we have;

Null Hypothesis; H0: μ ≥ 7

Alternative hypothesis; HA: μ < 7

B) Formula for the test statistic is;

z = (x - μ)/(s/√n)

Plugging in the relevant values, we have;

z = (6.7 - 7)/(2.1/√150)

z = -0.3/0.1715

z = -1.75

C) Using online p-value from z-score calculator attached with; z = - 1.75 ; α = 0.01 and one tailed distribution, we have;

The P-Value = 0.040059

Thus,the most appropriate answer is;

Option C: 0.025 ≤ p-value < 0.05

D) P-value is greater than the significance level, thus we fail to reject the null hypothesis.

E) We will conclude that there is insufficient evidence to suggest that Americans sleep less than the recommended 7 hours of sleep.

Answer:

answers below

Step-by-step explanation:

hi! you can plug in the x values given into the equation and solve for y to get your table values.

y=-1(0)+2

y=2

y=-1(1)+2

y=1

y=-1(3)+2

y=-1

y=-3/2 (-2) -1

y=2

y=-3/2 (0) -1

y=-1

y=-3/2 (2) -1

y=-4

hope this helps!

the theoretical probability choosing a purple marble out of a 2/3 bag is. The bag has 16 purple marbles. How many marbles are in
algol [13]

Answer:

24 marbles

Step-by-step explanation:

P( purple) = 2/3 = purple/total

                   2/3 = 16/total

Using cross products

                  2 * total = 3 *16

                    2 * total  = 48

                            total = 24

There are 24 marbles
