Kindly help me find solutions to all of the following questions please?

Question: A researcher predicts that there is an effect of domestic conflict on job performance. Hypothesis for

this research to mention the interest of the researcher clearly. Also, mention the hypothesis which will be tested

for this research. (In other words, write the null hypothesis and alternative hypothesis in words).

H0:_______________________________________________________________________________________

H1:_______________________________________________________________________________________

The confidence interval was 91% and the p-value was 0.09. How would you rephrase the hypothesis to publish

the result?

IE 331: Probability and Engineering Statistics Quiz # 2 Name: Fall 2019 (Section 2) ID: 1. A fair coin is flipped six times and the number of heads is counted. Calculate the probability of at least two heads. 2. Calculate the probability that the coin will land heads three or fewer. 3. Calculate the mean, and standard deviation of the binomial distribution.20. Probability-weighted means and standard deviations The previous section discussed calculating descriptive statistics using "ex post" (historical) data. This method is effective for describing past events. In addition, you can use historical results to characterize future events-that is, if you can reasonably assume that future events will resemble past events. However, if a reliable probability distribution is available, you can calculate expected descriptive statistics (also called "ex ante" statistics). The probability distribution describes all the possible outcomes a variable can assume. Using probability data, you can calculate the expected mean, variance, and standard deviation using the following formulas: a' - 2 P.(x- ") A probability distribution for five possible market conditions is shown below, along with the expected demand in each state. Calculate the expected value (mean) and standard deviation of demand. Market condition Probability Demand (Thousands of units) Terrible6. Suppose that the probability of being tutored in Statistics is 0.55, while the probability of being tutored in Physics is 0.32, and the probability of being tutored in both Statistics and Physics is 0.09. a) What is the probability of being tutored in Statistics or Physics? b) What is the probability of not being tutored in Statistics nor Physics? c) Are the events "being tutored in Statistics" and "being tutored in Physics" mutually exclusive?
