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.

Social media has changed the nature of social activism among students. Search the Internet for two other examples of teams of students using social media to promote a cause, protest, and/or address some social justice. In your initial posting address with each example, what was the goal of the students involved, and how do you think social media impacted students’ ability to achieve their goal? Do you feel that social media promotes or hampers activism among groups of students? Explain....

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...

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.
