Most adults would not erase all of their personal information online if they could. A software firm survey of 480 randomly selec ted adults showed that 35% of them would erase all of their personal information online if they could.Find the value of the test statistic?
1 answer:
Answer:
-7.90
Step-by-step explanation:
Let's write the null hypothesis (H0) and alternative hypothesis (Ha) from the claim statement
P = population proportion of adults who would erase all of their personal information online if they could
H_{0}:P=0.5
H1 P< 0.5
Let's write the given information:
n = sample size = 480
sample proportion =
formula of z test statistic for one sample proportion test is as follows:
plug the above values in the above formula we get
So that the test statistic value is -7.90 (Rounded up to two decimal places)

Step-by-step explanation:
- 5 ( p + 3 / 5 ) = - 4
- 5 p - 3 / 5 * 5 = - 4
- 5 p - 3 = - 4
- 5 p = - 4 + 3
- 5 p = - 1
therefore p = 1/ 5
First do 3x + -5x = -2x Then do -2x + 5x = 3x Lastly do 3x+1
Answer:
3/10 > 1/5
Step-by-step explanation:
3/10 = 1.5/5
or
1/5 = 2/10
3/10 > 2/10
1.5/5 > 1/5
Answer:
If the mean of four numbers is 7, we know that their sum is 7 * 4 = 28. We can use this information to find the last number. If the fourth number is x, we can write:
2 + 5 + 17 + x = 28
24 + x = 28
x = 4
