Faker is a known Esports gamer and an investor at the same time. His portfolio primarily tracks the performance of Tesla and Fakerhe wants to add the stock of GameStop Corp. (GME). Before adding GME to his portfolio, Faker wants to assess the correlation between the stock and Tesla to ensure that adding the stock won't increase the systematic risk of his portfolio. To find the coeficient, Faker gathers the following prices for the last five years: TESLA GME 2017 71.3 22.2 2018 79.6 16.5 2019 51.4 9.5 2020 489.6 12.7 2021 1033.42 183.3 What is the value of the critical Pearson correlation coefficient?

Carl is conducting a research study and finds a significant positive correlation between a state's per capita consumption of mozzarella cheese and the number of doctoral degrees in civil engineering that are awarded (real example!). However, this association is actually caused by a third variable that Carl did not measure. The relationship between cheese consumption and engineering degrees is an example of a(n): Group of answer choices spurious relationship clinically significant relationship univariate relationship negative correlation

Spurious correlation refers to the apparent relationship between variables that either have no true relationship or are related to other variables that have not been measured. One widely publicized stock market indicator that is an example of spurious correlation is the relationship between the winner of a major sports championship and the performance of a stock index in that year. The "indicator" states that when a team from a particular conference wins the championship, the stock index will increase in that year. Since the first championship was held, the indicator has been correct 36 out of 44 times. Assuming that this indicator is a random event with no predictive value, you would expect that the indicator would be correct 50% of the time. Complete parts (a) and (b) below. a. What is the probability that the indicator would be correct 36 or more times in 44 years? The probability is (Type an integer or decimal rounded to four decimal places as needed.)
A student noticed that when she gets less than 8 hours of sleep at night, she scores lower on her test grades. Can one conclude that this positive correlation shows a causal relationship? OYes, because it is well known that less sleep lowers test scores OYes, because it is not a negative correlation O No, because all students get less than 8 hours of sleep at night No, because it is possible that the student gets lower test grades because of another factor, such as not studying
