Life Expectancy by Year of Birth (For all questions)This table shows the life expectancy (y) for an individual born in the United States incertain years (x). There is an Excel spreadsheet provided that contains this data foryour calculations, if you wish to use it. IMPORTANT: values in the answer choiceswere calculated in Excel using the full decimals available and then rounded. This issignificant when you are using the equation for prediction with large numbers likeyears. You should use 3-4 decimal places for slope and 2 for intercept - and thenyour answer will be close enough to easily recognize the correct answer choice.Year of LifeBirthExpectancy193059.7194062.9195070.2196569.7197371.4198274.5198775199275.7201078.7

Visualize that two tributaries A and B at their confluence form a river C. Statistical properties of flow data for tributaries A and B indicate that tributary A has a yearly discharge rate smaller than its mean flow rate (?̅?) in 50% of the years while tributary B has a yearly discharge rate smaller than its mean flow rate (?̅?) in 60% of the time. In 70% of the years in which tributary A has a discharge rate smaller than its mean discharge rate (?̅?), tributary B also has a discharge rate smaller than its mean discharge rate (?̅?). Compute the probability that (i) both tributaries have a discharge rate smaller than their mean discharge rates, (ii) at least one tributary has a discharge rate smaller than its mean discharge rate, (iii) tributary A has a discharge rate smaller than its mean discharge rate given that tributary B has a discharge rate smaller than its mean discharge rate, (iv) at least one tributary has discharge rate higher than its mean discharge rate, and (v) probability…
Perform a complete analysis of this data using the plots and descriptive statistics you generated. You should write your analysis as though it is intended for someone who knows absolutely nothing about this data. You may use the following questions as a starting point to help guide your analysis: What do the data points in both columns represent? Are the data skewed? How do the data compare to one another? (Variation, median, etc.)
Here is the data to solve these 3 question. Please give me all this 3 questions answer.
Chi-square is different. Explain why it's different and what types of data require you to use chi-square for analysis. Please give an example.
What does this data tell you? Section 4 appears to be a challenge; remember you must compare data to the national data and determine if there are any statistically significant differences at the 0.5 level. For Table 4-1, Information for national is given in table 4-4. You must then comment if it is statistically significant. For table 4-2 and 4-3 you can use formulas with data from table 4-4 (hints below) to find the national and comment if it is statistically significant. Here is a hint: Table 4-2: National Medicare Reimbursement/National Number of Discharges = Average National Reimbursement Hope that helps! Let me know if you have any questions.

I use excel. I do not know what data anlysis toolpak to use, however, to find the answer, t stat, df, P, etc. I also don't know how to word Ho and Ha. Thanks! The data shown below are the initial weights and gains in weight (in grams) of female rats on a high protein diet from 24 to 84 days of age. The point of interest in these data is whether the gain in weight is related to (dependent on) the initial weight. If so, then feeding experiments on female rats can be made more precise by adjusting for differences in initial weights of the rats. Statistically test this with a regression analysis. Rat Number Initial Weight (gms) Weight Gain (gms) 1 50 128 2 64 159 3 76 158 4 64 119 5 74 133 6 60 112 7 69 96 8 68 126 9 56 132 10 48 118 11 57 107 12 59 106 13 46 82 14 45 103 15 65 104 What is the equation for the multiple regression? What is the best estimate of the amount of variance in Y which is due to its regression on the independent variables?
just the last part thank you
A study is conducted involving 17 infants to investigate the association between gestational age at birth, measured in weeks, and birth weight, measured in grams. By the used of the table what is the coefficient relationship between the gestational age at birth and birth weight of the infants? Please make a Decision and Conclusion, refer to the image below for interpretation.
