The distribution of final exam scores of all students taking Statistics at a large university are heavily skewed to the left with amean of 87% and a standard deviation of 8.5%.Describe the shape of the sampling distribution of x for SRSS of size n = 35 from the population of statistics students atthis university.Because n = 35 > 30, we do not have enough information to draw a conclusion about the shape of the samplingdistribution of x.Because n = 35 > 30, the sampling distribution of x will be skewed to the left even more strongly than the population.Because n = 35 > 30, the sampling distribution of x will be approximately normal.Because n = 35 > 30, the sampling distribution of x will be skewed to the left, but not quite as strongly as thepopulation.Because n =35 > 30, the sampling distribution of x will be skewed to the left just as strongly as the population.

Solution-: Given: Mean=μ=87 and SD=σ=8.5,n=35 We want to describe the shape of the sampling…

The GSS survey is conducted for approximately 2200 adults every year, since 1972 for a total of more than 38,000 participants. During several years of the GSS, participants were asked how many close friends they have. The mean for this variable was 7.44 friends, with a standard deviation of 10.98. The median was 5.00 and the mode was 4.00. What do the mean and standard deviation suggest about the shape of the distribution?
Suppose the true proportion of voters in the county who support a specific candidate is 0.43. Consider the sampling distribution for the proportion of supporters with sample size n = 127. What is the mean of this distribution? What is the standard error of this distribution? Please round to at least 3 significant figures.

The graph of the waiting time (in seconds) at a red light is shown below on the left with its mean and standard deviation. Assume that a sample size of 225 is drawn from the population. Decide which of the graphs labeled (a)-(c) would most closely resemble the sampling distribution of the sample means. Explain your reasoning. (a) (c) (b) = 12.9 SE AP(x) 0.04- 0 o = 12.9 iμ=X7.5 X 50 Time (in sec.) AP (X) -40 0.04- LA = 1.2 40 Time (in sec.) 0.04- -20 P(X) x = 12.9 = 17.5 X 50 Time (in sec.) Graph most closely resembles the sampling distribution of the sample means, because (Type an integer or a decimal.) μx = = AP (X) 0.55- o- = 0.86 x = 17.5 0 50 Time (in sec.) and the graph + is the same shape as the graph for the original distribution approximates a normal curve
The retirement age of National Football League (NFL) players is Normally distributed with a mean of 33 years and a standard deviation of 2 years. What percentage of NFL players retire before age 32? The distribution of average hours of sleep per weeknight among college students is found to be Normally distributed, with a mean of 6.5 hours and a standard deviation of 0.7 hour(s).

Phyllis, a college business student wants to study how many students in her class study for less than 20 hours per week. Past data reveals that the hours college students study per week has a mean of 29 with standard deviation 9 hours. The normal distribution for the population is shown by the dotted black line. She plans to take a random sample of 36 such college students and will calculate the mean hours studying to compare to the known hours studying. Compute the the mean and standard deviation of the sampling distribution of sample means for a sample of size 36. Round your answers to the nearest tenth. Show your answer by moving the two draggable points to build the sampling distribution.

find the sample variance for the following data set using xi and (xi^2) 20.2, 21.8, 17.6 , 21.6 , 19.5 , 19.8 , 18.6
A company has determined that the mean number of days it takes to collect on its accounts receivable is 36 with a standard deviation of 11 days. The company plans to select a random sample of n=12 accounts and compute the sample mean. The sampling process follows a simple random sampling. The objective of random sampling is to gather data that accurately represent a population. 2b. If we carefully follow the sampling plan, there is a possibility to obtain zero sampling error. Please comment on this statement.
Suppose that a study of elementary school students reports that the mean age at which children begin reading is 5.3 years with a standard deviation of 0.7 years. If a sampling distribution is created using samples of the ages at which 31 children begin reading, what would be the standard deviation of the sampling distribution of sample means?? Round to 2 decimal places if necessary.
Suppose that a sample of size 52 is drawn from a population with mean 23 and standard deviation 39 . Find the value of , the standard deviation of the distribution of sample means.
A researcher wants to determine the average height of students in a university using convenience sampling. They measure the height of 15 students selected based on their availability and accessibility. The mean height of these students is 170 cm with a standard deviation of 5 cm. Can the researcher use this sample to make inferences about the population of all students at the university?
