RESEARCH STUDY 4.1: Dr. Kushner is planning on conducting a study next semester. He is curious as to whether sleep deprivation i

s associated with poorer cognitive performance. For example, if you sleep poorly the night before a big exam, will you do worse? Dr. Kushner is especially curious about selective sleep deprivation, where people are kept from entering REM (rapid eye movement) sleep. Using an electroencephalograph (EEG) to monitor brain waves, he plans to let participants sleep until they enter REM sleep and then wake them. After the participants are awake for one minute, Dr. Kushner plans to let them return to sleep. As they enter REM sleep again, he will wake them again and follow the same procedure. He plans to do this through the entire eight-hour sleep session. The following morning, participants will be asked to take a sample SAT test. Dr. Kushner suspects that the people who will most benefit from his study are high school and college students, who are asked to perform cognitive functions in various states of sleep deprivation. Given this information, what type of participants should Dr. Kushner recruit for his study?

tatuchka [14]

Answer:  t=-5.651

Explanation:

Let \mu be the population mean number of hours a week answering their email.

As per given  we have

H_0: \mu\geq7\\\\ H_a: \mu

Sample size : n= 783

Sample mean : \overline{x}=5.54

Sample standard deviation: s=7.23

Since population standard deviation is unknown, so our test -statistic has a t-distribution.

Test statistic : t=\dfrac{\overline{x}-\mu}{\dfrac{s}{\sqrt{n}}}

=\dfrac{5.54-7}{\dfrac{7.23}{\sqrt{783}}}\\\\\\=\dfrac{-1.46}{0.2583791}\\\\\approx-5.651

∴ The test statistic : t=-5.651

ioda

Answer:    Muscle tone

Explanation:  Muscle tone is actually a muscle tension. This tension (muscle tone) maintains the body in its position as it is, or in a particular desired position. Or, for example, during movement, when the body changes its position, these changes of position are regulated by muscle tone. When the body is at rest, some muscle tension exists, and depending on the general fitness of the body, that tension under the skin is more visible or less visible, that is, my muscles will be tighter or floppy.
