Jessica knows that the adult population gets, on average, eight hours of sleep each night. A hypothesis test can help her see if
Nitella [24]

Answer:

-4.42

Step-by-step explanation:

Given the following :

Population mean (pm) = 8 hours

Sample mean (sm) = 6.9 hours

Number of observations (n) = 101 students

Sample standard deviation (sd) = 2.5

Using the t-statistic formula :

[(sm - pm) / (sd/√n)]

Hence,

[(6.9 - 8) / (2.5/√101)]

[(-1.1) / (2.5/10.05)]

-1.1 / 0.2487562

= −4.422

The test statistic = - 4.42 to the nearest hundredth.

Solve graphically the inequality \[ x ≥ 2 \]
Xelga [282]

1) Graph the corresponding equation \( x = 2 \); this will split the plane into two regions. One of the region represents the solution set.

2) Select a point situated in any of the two regions obtained and test the inequality. If the point selected is a solution, then all the region is the solution set. If the selected point is not a solution, then the other (second) region represents the solution set.

3) Test: In this example, let us for example select the point with coordinates (3 , 2) which is in the region to the right of the line x = 2. If you substitute x in the inequality \( x ≥ 2 \) by 3 it becomes \( 3 ≥ 2 \) which is a true statement and therefore (3 , 2) is a solution. Hence, we can conclude that the region to the right of the vertical line x = 2 is a solution set including the line itself which is shown as a solid line because of the inequality symbol \( ≥ \) contains the \( = \) symbol. The solution set is represented by the blue hash region in the graph below including the line x = 2.
