Answer: n >
Step-by-step explanation:
1. So, to understand this you need to understand that the opposite of 11 is -11.
2. Use the formula 3n+12>-11.
3. Subtract 12 from both sides (3n>-23)
4. Divide by 3 on both sides. (n>)
5. You can go a step further and simplify into -7.
6. n >
Answer:
The 95% confidence interval of the proportion of all adults that have high blood pressure is 0.17059 < < 0.314695
Step-by-step explanation:
The confidence interval for a proportion is given by the following formula;
Where:
x = 33
n = 136
= x/n = 33/136 = 0.243
z value for 95% confidence is 1.96
Plugging in the values, we have;
Which gives;
0.17059 < < 0.314695
Hence the 95% confidence interval of the proportion of all adults that have high blood pressure = 0.17059 < < 0.314695
From the above we have;
23.2 < x < 42.798
Since we are dealing with people, we round down as follows;
23 < x < 42.
