Answer: 99.73%
Step-by-step explanation:
Given : Mean : 
Standard deviation : 
Let X be the random variable that represents the data values.
Formula for Z-score : 
For x=94, we have

For x=106, we have

The probability that the samples are between 94 and 106:-

Hence, the percent of the samples are expected to be between 94 and 106 = 99.73%
I think the answer is N-4
Answer:
1. Yes
2. Yes
3. No
4. No
Step-by-step explanation:
4(-2) +9>-19 Multiply 4 and -2
-8+9>-19 Add -8 and 9
1 > -19 1 is greater than -19
4(5) +9>-19
20+9>-19
29>-19 29 is greater than -19
4(-10) +9>-19
-40+8>-19
-32>-19 -32 is not greater than -19
4(-7) +9>-19
-28+9>-19
-19>-19 -19 is not greater than -19
