Find the value of z such that 0.8664 of the area lies between −z and z. Round your answer to two decimal places.
Archy [21]

Using the normal distribution, the value of z is of z = 1.5.

<h3>Normal Probability Distribution</h3>

The z-score of a measure X of a normally distributed variable with mean \mu and standard deviation \sigma is given by:

Z = \frac{X - \mu}{\sigma}

  • The z-score measures how many standard deviations the measure is above or below the mean.
  • Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.

For this problem, considering the symmetry of the normal distribution, the area above the mean is given by:

0.8664/2 = 0.4332.

Hence <u>z has a p-value of 0.5  + 0.4332 = 0.9332</u>, hence the value of z is z = 1.5.

PolarNik [594]

Let's solve your equation step-by-step.<span><span><span> 44−1</span>+<span>7q</span></span>=106</span>

Step 1: Simplify both sides of the equation.<span><span><span> 44−1</span>+<span>7q</span></span>=106</span><span>
</span><span>Simplify: (Show steps) </span><span><span><span><span>44+</span>−1</span>+<span>7q</span></span>=106</span><span><span><span>(<span>7q</span>)</span>+<span>(<span>44+<span>−1</span></span>)</span></span>=106 </span>(Combine Like Terms)<span><span><span>7q</span>+43</span>=106</span><span><span><span>7q</span>+43</span>=106</span>
