Solved 4 Suppose Act Mathematics Scores Are Normally Chegg Suppose act mathematics scores are normally distributed with a mean of 21 and a standard deviation of 5.3 . a university plans to send letters of recognition to students whose scores are in the top 7% . what is the minimum score required for a letter of recognition? round your answer to the nearest tenth, if necessary. Calculate the z score corresponding to the top 30% by finding the z score that corresponds to 70% in the standard normal distribution table. the closest value is 0.524.
Solved Suppose Act Mathematics Scores Are Normally Chegg Suppose act mathematics scores are normally distributed with a mean of 20.8 and a standard deviation of 5.4. a university plans to admit students whose scores are in the top 30%. The z score formula is: z = (x μ) σ where z is the z score, x is the score we want to find, μ is the mean, and σ is the standard deviation. Step by step explanation: suppose act mathematics scores are normally distributed, we would apply the formula for normal distribution which is expressed as z = (x µ) σ where x = act mathematics scores. µ = mean score σ = standard deviation from the information given, µ = 21.3 σ = 5.3. Emily scores 7 0 0 on the mathematics part of the sat. the distribution of sat scores in a reference emean 5 0 0 and standard deviation 1 0 0 michael takes the american college testing (act) mathem scores are normally distributed with mean 1 8 and standard deviation 6 find the standardized score e (use decimal notation.

Find the z score corresponding to the top 11% using the standard normal distribution table. the z score for the top 11% is approximately 1.23. round the minimum score required to the nearest tenth. 😉 want a more accurate answer? get step by step solutions within seconds. Nine scores are reported for the mathematics section: a score for the section overall and eight reporting category scores based on specific mathematical knowledge and skills. The z score for the 95th percentile is approximately 1.645. now, we can use the z score formula to find the minimum score required for the scholarship: $z = \frac {x \mu} {\sigma}$ where $z$ is the z score, $x$ is the score, $\mu$ is the mean, and $\sigma$ is the standard deviation. Suppose act mathematics scores are normally distributed with a mean of 20.8 and a standard deviation of 5.4. a university plans to admit students whose scores are in the top 30%. what is the minimum score required for admission? round your answer to the nearest tenth, if necessary. there are 2 steps to solve this one.
