The probability of a certain candidate to get elected is 0.4. what is the probability tgat the candidate will lose the election?
a.0.6
b.0.4
c.0.2
d.0.8
A pollster decides to find the candidates electability by conducting a survey vonsisting of 1000 participants. can the pollster assume that the survey reaults would approximate a normal diatribution?
a. no because the sample is too small, and the data is discrete.
b. yes, because the sample size is enough, the data is continuous.
c. yes, because the sample size is enough, and the data is discrete.
d. no because the sample os too small, and the data is continuous.
Assume the data follows a normal diatribution with a standard deviation of 40. What is the value for u and ox?
a. 400,1,2649
b.400,40
c.40,40
d. 40,1,2649

College students and STDs: A recent report estimated that 25% of all college students in the United States have a sexually transmitted disease (STD). Due to the demographics of the community, the director of the campus health center believes that the proportion of students who have a STD is lower at his college. He tests H0: p = 0.25 versus Ha: p < 0.25. The campus health center staff select a random sample of 50 students and determine that 18%...

Bags of a certain brand of potato chips say that the net weight of the contents is 35.6 grams. Assume that the standard deviation of the individual bag weights is 5.2 grams. A quality control engineer selects a random sample of 100 bags. The mean weight of these 100 bags turns out to be 33.6 grams. Use this information to answer the questions below. 1. We can use a normal probability model to represent the distribution of sample means for...
