Question

what are some statistics research questions that involve college students and social media?

Answer #1

1. first in case of regression analysis if we have eeror in measurements in variables in y ,then we still don't have the degree in measurement error like how much variables are deviated from the true value we still don't have any criteria to measure it and matter of researcher's choice.

2. In case of inferencial statistics it has been seen that minimal sufficient statistic generally exists for every parameter.so the researchers are still busy in finding under what kind of situations minimal sufficient statistic may not exists.

3.reseach regarding instrumental variables are recently a buzz topic for statisticians in modern days.

A recent findings reported that college students spend an
average of 4.5 hours on social media per person per day. The
population standard deviation is 2.5 hours per day. A researcher
took a random sample of 120 college students for making inferences
about the population of college students. Answer the following
questions about the sampling distribution of sample mean of number
of hours on social media.
1) The mean of this sample of n=120 belongs to a sampling
distribution. What...

Suppose 5% of college students don’t use social media. We
randomly sampled 1000 college students.
a. Let X denote the number of students who don’t use social
media in this sample. Calculate the expected value and the standard
deviation for X.
b. Find the probability of observing 50 or less students who
don’t use social media in this sample. If you would like to use
normal approximation for binomial distribution, make sure to check
the conditions and you don’t need...

Is there a difference between community college statistics
students and university statistics students in what technology they
use on their homework? Of the randomly selected community college
students 43 used a computer, 72 used a calculator with built in
statistics functions, and 65 used a table from the textbook. Of the
randomly selected university students 28 used a computer, 33 used a
calculator with built in statistics functions, and 40 used a table
from the textbook. Conduct the appropriate hypothesis...

New research on the effects of social media usage has been
mixed. Some studies have found that social media helps people stay
connected to others, and can be a positive source of social
support. Other studies have found that social media makes people
feel lonely and unhappy. I decide to do my own study to see whether
social media has an effect on how many close friends people have. I
conduct an internet survey of 1000 people and ask them...

what are some other pressures that college students face? What
are some strategies that students can use to overcome college
pressures?

25 randomly selected students took a survey on how long they
spent on social media. The mean number of minutes these students
spent on social media was 205.1 minutes with a standard deviation
of 150 minutes.The population of the time spent on social media is
normally distributed. Construct a 98%confidence interval for the
population standard deviation of the time students spend on social
media.

Explain why companies seem to be fascinated by digital and
social media. What are some of the factors that might support this
thinking? What are some that might lead to considering it
misdirected?
