A field test for a new exam was given to randomly selected seniors. The exams were graded, and the sample mean and sample standa
RUDIKE [14]
"nine times out of ten" means we have 9/10 = 0.90 = 90% confidence interval. 

The center of each interval is 0.80 as this is the mean test score. The margin of error is 0.06 from the statement "within 6% of...". Put another way, the teacher is basically saying that they are 90% confident to find a test score between 74% and 86%

This is because
0.8 - 0.06 = 0.74
0.8 + 0.06 = 0.86

So that's why the confidence interval is (0.74, 0.86)

PSYCHO15rus [73]

Answer:

Step-by-step explanation:

3)\frac{5x}{2}+125 = 180\\\\\frac{5x}{2}=180-125\\\\\frac{5x}{2}=55\\\\        5x    = 55*2\\\\          x    =\frac{55*2}{5}\\\\         x = 11*2 = 22

4) 3x+ 42 + 90= 180

3x + 132 = 180

        3x = 180 -132

        3x = 48

          x = 48/3

         x = 16
