Respiratory Rate Researchers have found that the 95 th percentile the value at which 95% of the data are at or below for respiratory rates in breath per minute during the first 3 years of infancy are given by y=101.82411-0.0125995x+0.00013401x2 for awake infants and y=101.72858-0.0139928x+0.00017646x2 for sleeping infants, where x is the age in months. Source: Pediatrics. a. What is the domain for each function? b. For each respiratory rate, is the rate decreasing or increasing over the first 3 years of life? Hint: Is the graph of the quadratic in the exponent opening upward or downward? Where is the vertex? c. Verify your answer to part b using a graphing calculator. d. For a 1- year-old infant in the 95 th percentile, how much higher is the walking respiratory rate then the sleeping respiratory rate? e. f.

How do I put this in a scatter plot with per-capita real GDP in 1960 (relative to the USA in 1960) on the horizontal axis and the average per-capita growth rate of GDP on the vertical axis? Also when you hover over the separate points would it show what the country code is?
The consumption function captures one of the key relationships in economics. It expresses consumption as a function of disposal income, where disposable income is income after taxes. The attached file “Regression–Dataset1” shows data of average US annual consumption (in $) and disposable income (in $) for the years 2000 to 2016. a)what is the Pearson correlation value between income and consumption? Select one: a. 0.791 b. 0.109 c. None of the above d. 0.978

Cost Behavior and Correlation Analysis PC's total maintenance cost for the past 10 months is Php50,000.00. Some of the maintenance activity appears related to the operation of machinery, and the accountant wants to determine whether machine hours should be used as a basis upon which to estimate maintenance cost at various levels of capacity. Machine hours for the same period totalled 40,000 hours. The machine hour differences from average multiplied by the maintenance cost differences from its average and summed E(x¡ – x)(yi – ỹ) is 2,400. The machine hour differences from average squared and summed E(x¡ –x)² is 6,250, and the maintenance cost differences from average squared and summed E(yi – y)² is 1,000. Required: 1. Compute the coefficient of correlation, r, and the coefficient of determination,r2, for maintenance cost and machine hours. 2. Compute the variable maintenance cost per machine hour, using the method of least squares. 3. Compute the fixed maintenance cost, using the…

For this question, create a new column in the dataset where total rainfall is just the sum of our three separate rainfall variables. (Solve this question by Excel and Autocorrelation knowlege) (a) plot crop yield vs. time. Does yield appear to be stationary? Why or why not? (b) plot total rainfall vs. time. Does total rainfall appear to be stationary? Why or why not? (c) plot the first-difference of crop yield vs. time. Does this series appear to be stationary? Why or why not? (d) formally test whether crop yield, rainfall and the first-difference of crop yield are stationary using the appropriate test. Be sure to do all parts of the hypothesis tests. After these tests, what can you say the order of integration is for each of the variables?(e) estimate a model where yield is a function of rainfall and time. You do not have to worry about the time variable being stationary or not, but the other two must be stationary (you might need to difference one or both of them to make it…
