Ralphâs Bookstores have indicated that the annual gross revenue for their stores has a standard deviation of Ï=$50,000. Blank #1: Given a sample size of 25 and a sample mean of $270,000, create a 90% confidence interval for estimating the population mean annual gross revenue. Enter your answer as lower bound, upper bound with no extra spaces and bounds rounded to nearest whole number.
Given a sample size of 25 and a sample mean annual gross revenue of $270,000, conduct a hypothesis test with a 0.10 level of significance to show that the population mean number of boxes sold is different from $250,000.
Blank #2: Report the p-value of the test to 4 decimal places.
These procedures support each other because the value of $250,000 is (Blank #3: not in or in) the confidence interval and the p-value of the test is (Blank #4: smaller than or not smaller than) level 0.10.

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.

step-by-step explanation: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.

step-by-step explanation:

we are given a graph for system of inequalities.

in order to write the system of inequalities for the given graph, we need to find the inequality for each of the line separately.

let us find the slope of dotted line first.

taking two coordinates on the graph.

let us say (0,0) and (3,1).

let us find the slope of the line now.

slope of the dotted line would be =.

y-intercept of dotted line is y=0 only.

plugging slope m= and b=0 in slope-intercept form y=mx+b, we get

.

the line is shaded up of that dotted line.

therefore, for shading up we would take greater than inequality symbol > .

and because it's a dotted line we would take only > symbol in place of = sign in above equation of line.

therefore, inequality for dotted line would be

let us take two points (3,1) and (0,4) on the solid line.

slope of the solid line would be =.

for the solid line we have y-intercept b= 4.

plugging slope m= -1 and b=4 in slope-intercept form y=mx+b, we get

y = -1x + 4.

the line is shaded down of that solid line.

therefore, for shading down we would take less than inequality symbol < .

and because it's a solid line we would take ≤ symbol in place of = sign in above equation of line.

therefore, inequality for solid line would be

greater than one
