WebRealize P (z ≤ -1.83) = P (z ≥ 1.83) since a normal curve is symmetric about the mean. The distribution for z is the standard normal distribution; it has a mean of 0 and a standard deviation of 1. For Ha: p ≠ 26, the P-value would be P (z ≤ -1.83) + P (z ≥ 1.83) = 2 * P (z ≤ … WebSince the total area under any normal curve is 1, it follows that the areas on either side of z = 0 are both 0.5. Also, according to the Standard Deviation Rule, most of the area under the standardized curve falls between z = -3 …

They found that the maximum speed had a normal distribution with a mean of 29 mph and standard deviation of 1.4 mph. Consider randomly WebWe want to find P($20,000 X ≤ $30,000). To solve, let Z = (X - $25,000)/$10,000. Note that when x = $20,000, z = ($20,000 - $25,000)/$10,000 = -0.5, and when x = $30,000, z = +0.5. Hence, P($20,000 ≤ X ≤ $30,000) = P(-.5 ≤ Z ≤.5) = 2F(.5) - 1 = 1.383 - 1 = .383. Thus, about 38% of the taxpayers will benefit from the new law. V. fast growing edible plants
