Claim: Most adults would erase all of their personal information online if they could. A software firm survey of randomly selected 583 adults showed that 58 % of them would erase all of their personal information online if they could. Find the value of the test statistic.

Test statistic = 3.863

Step-by-step explanation:

We are told that most adults would erase all of their personal information online if they could. Since the word "most" is used, it means more than 50% or 50 percent.

So, p_o = 0.5

Also, we are told that 58 % of them would erase all of their personal information online if they could.

Thus, p^ = 0.58

Number of randomly selected adults; n = 583

The test statistic formula for hypothesis test for proportion is given by:

z = (p^ - p_o)/[√[p_o(1 - p_o)/n]

Plugging in the relevant values, we have;

z = (0.58 - 0.5)/[√[0.5(1 - 0.5)/583]

z = 0.08/0.02070788416

z = 3.863

So for a shape with a certain amount of sides, there will always be a fixed number for the internal angles.

For example, a triangle must have 180 degrees of internal angles.

A square must have 360.

The formula therefore is, (if s equals the side number)

180(s - 2)

And s here is 6

So,

180 * 4

Or, 720

So all those numbers need to add up to 720.

So we can just add up these.

160 + 75 + 108 + 113 + 132

Or, 588.

Now since we know they have to add up to 720, but we only have 588, we need to figure out how much more we need.

720 - 588 = 132

So x = 132.
