Some IQ tests are standardized to a Normal model N(100,19). What is the cutoff value for the top 5% of all IQs
Montano1993 [528]

Answer:

The cutoff value for the top 5% of all IQs is 131.255.

Step-by-step explanation:

When the distribution is normal, we use the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by:

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

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this question, we have that:

\mu = 100, \sigma = 19

What is the cutoff value for the top 5% of all IQs

This is the 100 - 5 = 95th percentile, which is X when Z has a pvalue of 0.95. So X when Z = 1.645.

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

1.645 = \frac{X - 100}{19}

X - 100 = 19*1.645

X = 131.255

The cutoff value for the top 5% of all IQs is 131.255.

If we were conducting an experiment to test a hypothesis that people with religious backgrounds engage in more altruistic behavi
jasenka [17]

Answer:

a. People with less religious backgrounds engage in less altruistic behavior than people with nonreligious histories, or there is no difference between the groups with respect to altruistic behavior.

Correct, that's what we try to proof, and on this case this statement present how we need to put the null hypothesis and we have the key word "there is no difference" that is important to use when we create the null hypothesis for this type of test.

Step-by-step explanation:

Previous concepts

The null hypothesis attempts "to show that no variation exists between variables or that a single variable is no different than its mean"

The alternative hypothesis "is the hypothesis used in hypothesis testing that is contrary to the null hypothesis"

Solution to the problem

We want to proof that "people with religious backgrounds engage in more altruistic behavior than nonreligious people"

Assuming that we have the following options, we select one based on the info provided.

a. People with less religious backgrounds engage in less altruistic behavior than people with nonreligious histories, or there is no difference between the groups with respect to altruistic behavior.

Correct, that's what we try to proof, and on this case this statement present how we need to put the null hypothesis and we have the key word "there is no difference" that is important to use when we create the null hypothesis for this type of test.

b. People with religious backgrounds are more altruistic than people with nonreligious backgrounds.

That's not at all False, but the problem is that we don't specify if we have differences or not betwen the two groups, for this case is not the best answer.

c. People with nonreligious backgrounds are more altruistic than people with religious backgrounds.

That's not true since we are trying to proof the inverse statement. "people with religious backgrounds engage in more altruistic behavior than nonreligious people"

d. There would be no null hypothesis for this experiment.

False that's not correct, we have a null and alternative hypothesis for this case.
