Step-by-step explanation:
Given that in testing the reliability of DNA results used in crime labs, the new procedure matched DNA results to suspects 46 out of 50 times.
i.e population proportion = 46/50 = 0.92
For 99% success rate
Here p the proportion follows normal distribution with mean = 0.92 and
Std error =
Margin of error for 99% = ±2.58*0.038 = ±0.099
Confidence interval lower bound = 0.92-0.099 = 0.8210
Upper bound = 0.92+0.0999 ~1
so Confidence interval - (0.821,1)
(p cannot exceed 1 so 1 is taken)
We are 99% sure the that this new DNA match procedure correctly identifies susspects between (0.821, 1)
since 99% confidence interval contians 1, there is evidence at the .01 level that this procedure will successfully match DNA results 99% of the time
Answer:
Step-by-step explanation:
First, find the area of the bigger shape. Then, separately, find the smaller shape's area. Subtract the smaller one by the big boi, and you'll get the area of the shaded area. You can count the little squares too.
12*8=96
4*6=24
96-24=72
No.
