here is my question, just answer

Question 1 I have a new hobby - a saltwater fish tank that will contain mostly live corals (called a reef tank). I am currently in the planning stage and am gathering knowledge to give me the best chance of success with my tank. As part of the planning stage, I reached out to 50 experienced Central Florida reefers (people who currently have a reef tank) and asked them to provide the following information: Size of the tank (in gallons), Type of Lighting used (Florescent, LED, Hybrid, or Other), whether it is their first tank (Yes or No), and how long (in years) they have been in the hobby. I want to estimate the average fish tank size of all Central Florida reefers. Here is my Statistix printout: Descriptive Statistics Variable N Lo 948 CI Mean Up 949 CI Give a theoretical interpretation of the confidence level used in this printout. In repeated sampling. 94% of the intervals created will contain the population mean. O 94% of the population tween 59.972 and 82.548 gallons. O In repeated sa he interval. O 94% of the tar etween 59.972 and 82.548 gallons. Question 2 2 pts I have a new hobby - a saltwater fish tank that will contain mostly live corals (called a reef tank).

As part of the planning stage, I reached out to 50 experienced Central Florida reefers (people who currently have a reef tank) and asked them to provide the following information: Size of the tank (in gallons), Type of Lighting used (Florescent, LED, Hybrid, or Other), whether it is their first tank (Yes or No). and how long (in years) they have been in the hobby. I want to estimate the average fish tank size of all Central Florida reefers. Here is my Statistix printout: Descriptive Statistics Variable N Lo 948 CI Size Mean Up 949 CI 59.972 71.260 41.455 A buddy of mine claims that the average tank size of all Central Florida reefers is 60 gallons. How should I respond to his claim? O At the 94% confidence level, the average tank size of all Central Florida reefers might be 60 gallons. We are 94% confident that the average tank size of all Central Florida reefers exceeds 60 gallons. We are 94%% confident that the average tank size of all Central Florida reefers equals 60 gallons. Question 3 I have a new hobby - a saltwater fish tank that will contain mostly live corals (called a reef tank). I am currently in the planning stage and am gathering knowledge to give me the best chance of success with my tank. As part of th planning stage, I read (people who currently have a reef tank) and asked them to provide the following information: Size of the tank (in gallons), Type of Lighting used (Florescent, LED, Hybrid, or Other), whether it is their first tank (Yes or No), and how long (in years) they have e been in the hobby. I want to estimate the average fish tank size of all Central Florida reefers. Here is my Statistix printout: Descriptive statistics Variable Size Lo 948 CI $9.972 Mean Up 946 CI 82.548 41.455 State whether the following assumptions are needed or not needed for the nterval given to be valid? We need a random sar Central Florida reefers [ Choose The tank size of all Central Florida reefers needs to be approximately [ Choose ] normally distributed Question 4 I have a new hobby - a saltwater fish tank that will contain mostly live coral (called a reef tank). I am currently in the planning stage and am gathering knowledge to give me the best chance of success with my tank. As part of th planning stage, I reached out to 50 ex enced Central Florida reefer (people who currently have a reef tank) and asked them to provide the following information: Size of the tank (in gallons), Type of Lighting used Florescent, LED, Hybrid, or Other), whether it is their first tank (Yes or No) and how long (in years) they have b want to estimate the average fish tank size of all Central Florida reefers. Here is my Statistix printout: Descriptive Statistics Variable 59.972 71.260 Up 946 CI 82.548 1.455 State whether the following will either increase or decrease the confidence interval width shown in the printout. 90% Change the confidence level to [ Choose ] Sample 20 more Central Florida reefers to include in the sample [ Choose ] Question 5 I have a new hobby - a saltwater fish tank that will contain mostly live corals (called a reef tank). I am currently in the planning stage and am gathering knowledge to give me the best chance of success with my tank. As part of the planning stage, I reached out to 50 experienced Central Florida reefers people who currer following information: Size of the tank (in gallons), Type of Lighting used Florescent, LED, Hybrid, or Other). whether it is their first tank () and how long (in years) they have been in the hobby. The confidence interval question was further broken down according to whether this was the first tank (yes or no) of the Central Florida reefer sampled. The results are here: Descriptive Statistics of Size by First_Tan First_Tan N Lo 978 CI Mean Up 978 CI SD Yes 35 0385 50.364 60342 13.094 What assumptions are necessary for interpreting the confidence interval for he "Yes" group? Both of these ass O The tank size distribution of all first tank Central Florida reefers needs to be approximately normally distributed. Neither of these assumptions are needed We need a random sample of first tank Central Florida reefers Question o I have a new hobby - a saltwater fish tank that will contain mostly live corals ( reef tank].
