A group of 121 Internet users 50-65 years of age were randomly chosen and asked to report the weekly number of hours they spend
1 answer:
Answer: We support the null hypothesis.
Step-by-step explanation:
Given : The purpose of the study was to determine whether the mean weekly number of hours that Internet users in that age group spend online differs from the mean for Internet users in general which is 12.50 hours.
The set of hypothesis for the given claim :-
A 95% confidence interval for the mean weekly number of hours that Internet users in that age group spend online was calculated to be (11.439 , 12.577).
Since 12.50 contained in the 95% confidence interval (11.439 , 12.577).
Therefore, we support the null hypothesis.
So the final conclusion will be, we have evidence to support the claim that Internet users in that age group spend online differs from the mean for Internet users in general which is 12.50 hours.

we conclude that the linear equation represented by the given table is:
y = (1/2)*x + 2
<h3>Which function is the one described by the table?</h3>A general linear equation is given by:
y = a*x + b
Where a is the slope and b is the y-intercept.
If the line passes through (x₁, y₁) and (x₂, y₂), then the slope is given by:
Here we can use just the first two points on the given line:
(-8, -2) and (-4, 0)
Then the slope will be:
Then the linear equation is something like:
y = (1/2)*x + b
To find the value of b, we can use one of the two given points, I will use (-4, 0), then:
0 = (1/2)*(-4) + b
0 = -2 + b
2 = b
Then we conclude that the linear equation represented by the given table is:
y = (1/2)*x + 2
Then the correct option is the first one.

Answer:
b =
Step-by-step explanation:
Using the rule of logarithms
log ⇔ nlogx
Given
190 = ( take the natural log ln of both sides )
ln190 = ln = bln200 ( divide both sides by ln200 )
= b
