Need help asap please. I believe my answers are correct but just need a second opinion. The distribution of actual weights of 8-oz chocolate bars produced by a certain machine is normal with mean 7.8 ouncesand standard deviation 0.13 ounces.Round your z-score to 2 decimal places.(a) What is the probability that the average weight of a bar in a Simple Random Sample (SRS) with four of these chocolate bars isbetween 7.7 and 7.93 ounces? Give your answer to at least 4 decimal places.ANSWER: 0.9155(b) For a SRS of four of these chocolate bars, what is the level L such that there is a 2% chance that the average weight is less thanL? Give your answer to at least 3 decimal places.ANSWER: 7.667

I need help with just part c. Someone on here already answered it for me but I'm really confused as there are steps missing and I'm not sure what to put in the calculator. " The first quartile separates the lowest 25% of the observations from the higher 75% of the observations. The first quartile is denoted by Q1. The second quartile separates the lower 50% of the observations from the higher 50% of the observations. The second quartile is denoted by Q2.The second quartile is same as median. The third quartile separates the lowest 75% of the observations from the higher 25% of the observations. The third quartile is denoted by Q3. The third quartile can obtained as follows...." Third Quartile is 1 somehow, and I don't understand how it is.
Please explain and show ALL WORK! Please don't give handwrittten answer..thanku A sample of trout caught in a pond included 400 small fish and 100 adult fish (of adequate size). The 400 small fish were then returned to the pond. In addition, 1000 small fish were put in the pond. A few days later, another catch totaled 410 small fish and 80 adult fish. Estimate the number of trout in the pond after the second catch.
Please solve the following attached question and round as needed in parts a and b. In part b, options for H0 and H1 null and alternatives hypotheses are: There is no lack of fit for the model A linear model would fit the data better than a quadratic model A cubic model would fit the data better than a quadratic model An exponential model would fit the data better than a quadratic model There is a lack of fit for the model
Certain car manufacturers install a gauge that tells the driver how many miles they can drive until they will run out of gas. A study was conducted to test the accuracy of these gauges. Each driver was assigned a certain gauge reading until empty to watch for. When their car announced it had that many miles remaining until empty, they began to measure their distance traveled. After they ran out of gas, they reported the distance they were able to drive (in miles) as well as the gauge reading they were assigned (in miles). Here is computer output showing the regression analysis: Identify and interpret the slope of the regression line used for predicting the actual distance that can be driven based on the gauge reading. (A) Slope = 1.1889. The predicted distance the drivers were able to drive increases by 1.1889 miles for each additional mile reported by the gauge. (B) Slope = 0.0457. The predicted distance the drivers were able to drive increases by 0.0457 miles for each additional…
The Conch Café, located in Gulf Shores, Alabama, features casual lunches with a great view of the Gulf of Mexico. To accommodate the increase in business during the summer vacation season, Fuzzy Conch, the owner, hires a large number of servers as seasonal help. When he interviews a prospective server, he would like to provide data on the amount a server can earn in tips. He believes that the amount of the bill and the number of diners are both related to the amount of the tip. He gathered the following sample information. Customer Amount of Tip Amount of Bill Number of Diners Customer Amount of Tip Amount of Bill Number of Diners 1 $ 7.00 $ 48.97 5 16 $ 3.30 $ 23.59 2 2 4.50 28.23 4 17 3.50 22.30 2 3 1.00 10.65 1 18 3.25 32.00 2 4 2.40 19.82 3 19 5.40 50.02 4 5 5.00 28.62 3 20 2.25 17.60 3 6 4.25 24.83 2 21 5.50 44.47 4 7 0.50 6.24 1 22 3.00 20.27 2…
