I need solution just for part B, and question 2, please. Part A: Roll a single die 50 times and record the results. Now use that data set to compute the mean, median, mode, variance, and standard deviation of the set. Part B: Then Calculate the 95% confidence interval for the mean. Question 2- What is the relationship between confidence intervals and levels of significance?

Topic 5: My Living Room For this discussion, select a room in your house (not a small room such as utility room or bathroom) and give us the name and dimensions of the room (please make the dimensions different from one your classmate has given even if it means adding (or subtracting) a foot from the length/width). Then compute:1. The area of the selected room in the house, in square feet. Be sure to give the dimensions of your room (rounded to the nearest foot) and show your computations.2. Calculate the price to buy and install the following: wood flooringcarpettileFor the room you have selected. Assume that the price for wood flooring is $4.98 per square foot, tile is $9.99 per square foot, and carpet is $3.99 per square foot (pad included). The cost of installation is $2.00 per square foot for each of the above options. Show computations for all options (material and installation).3. When you have completed your calculations, put into the final format specified below: Total square footage of room:Total price of renovation for the option you selected:Which option would YOU select and WHY?Instructions: Your initial post should 250 or more words.

1. Assume that the data has a normal distribution and the number of observations is greater than fifty. Find the critical z value used to test a null hypothesis.α = 0.05 for a two-tailed test.2. Assume that the data has a normal distribution and the number of observations is greater than fifty. Find the critical z value used to test a null hypothesis.α = 0.09 for a right-tailed test.3. Assume that the data has a normal distribution and the number of observations is greater than fifty. Find the critical z value used to test a null hypothesis.α = 0.05 for a left-tailed test.4. Assume that the data has a normal distribution and the number of observations is greater than fifty. Find the critical z value used to test a null hypothesis.α = 0.1 for a two-tailed test.5. Determine whether the hypothesis test involves a sampling distribution of means that is a normal distribution, Student t distribution, or neither.Claim: μ = 959. Sample data: n = 25, = 951, s = 25. The sample data appear to come from a normally distributed population with σ = 28.6. Determine whether the hypothesis test involves a sampling distribution of means that is a normal distribution, Student t distribution, or neither.Claim: μ = 119. Sample data: n = 15, = 103, s = 15.2. The sample data appear to come from a normally distributed population with unknown μ and 7. Determine whether the hypothesis test involves a sampling distribution of means that is a normal distribution, Student t distribution, or neither.Claim: μ = 78. Sample data: n = 24, = 101, s = 15.3. The sample data appear to come from a population with a distribution that is very far from normal, and σ is unknown.8. Find the P-value for the indicated hypothesis test.A medical school claims that more than 28% of its students plan to go into general practice. It is found that among a random sample of 130 of the school's students, 32% of them plan to go into general practice. Find the P-value for a test of the school's claim.9. Find the P-value for the indicated hypothesis test.In a sample of 88 children selected randomly from one town, it is found that 8 of them suffer from asthma. Find the P-value for a test of the claim that the proportion of all children in the town who suffer from asthma is equal to 11%.10. Find the P-value for the indicated hypothesis test.In a sample of 47 adults selected randomly from one town, it is found that 9 of them have been exposed to a particular strain of the flu. Find the P-value for a test of the claim that the proportion of all adults in the town that have been exposed to this strain of the flu is 8%.
