For a confidence interval with level C, the value p is equal to (1-C)/2. A 95% confidence interval for the standard normal distribution, then, is the interval (-1.96,1.96), since 95% of the area under the curve falls within this interval. <span>The point estimate for the </span>population proportion<span> is the sample proportion, and the margin of error is the product of the Z value for the desired confidence level (e.g., Z=1.96 for </span>95%<span> confidence) and the standard error of the point </span>
Answer: Well, Your best answer will be is 35. Here's a Explain. W-5=0 W=5 That's for the width. L=3*5-8 L=15-8=7 And, That's for the length. Here's proof. 35=7*5 35=35 Hope That Helps!~
