With age, the prefrontal cortex shrinks more than other parts of the brain

You want to find the 95% confidence interval for the mean of a distribution. What technique can

you use to find this interval? A) search a table for z scores that occur at 47.5% above the mean, and 47.5% below the mean B) calculate the standard deviation of the distribution and multiply by .95 C) determine the kurtosis of the distribution and compare against a table of means D) There is no way to determine a confidence interval for the mean of a distribution.

Identify the correct pathway by which auditory information flows to the brain

a. auditory nerve –> superior olivary nuclei –> medial geniculate –> superior colliculus –> auditory cortex b. auditory nerve –> cochlear nuclei –> medial geniculate –> auditory cortex c. auditory nerve –> cochlear nuclei –> superior olivary nuclei –> inferior colliculus –> medial geniculate –> auditory cortex d. auditory nerve –> cochlear nuclei –> superior olivary nuclei –> medial geniculate –> auditory cortex e. auditory nerve –> cochlear nuclei –> superior colliculus –> lateral geniculate –> auditory cortex
