A world wide fast food chain decided to carry out an experiment to assess the influence of income on number of visits to their restaurants or vice versa. A sample of households was asked about the number of times they visit a fast food restaurant (X) during last month as well as their monthly income (Y). The data presented in the following table are the sums and sum of squares. (use 2 digits after decimal point) ∑ Y = 393 ∑ Y2 = 21027 ∑ ( Y-Ybar )2 = SSY = 1720.88 ∑ X = 324 ∑ X2 = 14272 ∑ ( X-Xbar )2 = SSX = 1150 nx=8 ny=11 ∑ [ ( X-Xbar )( Y-Ybar) ] =SSXY=1090.5 PART A Sample mean income is Answer Sample standard deviation of income is Answer 90% confidence interval for the population mean income (hint: assume that income distributed normally with mean μ and variance σ2) is [Answer±Answer*Answer] 90% confidence interval for the population variance of income (hint: assume that income distributed normally with mean μ and variance σ2) is…

A new shoe company claims that their new Jumpalícious sneakers will help all wearers jump significantly higher. A group of basketball coaches wish to test this claim at the a = 0.05 tevel of significance. A random sample of players jumped with their current sneakers on, the maximum height reached was recorded, then the same group of players put on the Jumpalicious sneakers and jumped again, recording the maximum height reached. The 'old shoe' and new shoe' data is given below. Let Ho be the mean height reached by players wearing their old sneakers, uN be the mean height reached by players wearing the new sneakers, and 4 = EN - Ho. Assume that the jump differences have a normal distribution. (Round your results to three decimal places) Which would be correct hypotheses for this test? O Ho: p4 + 0, H:µa = 0 Ho: H4 = 0, H1 :Hd > 0 Ho: H4 = 0, Hị :Ha 0 Ho: 4 > 0, H1 : Hd < 0 O Ho: H4 = 0, H:Ha < 0 Maximum Height reached (inches): wearing old shoes wearing Jumpalicious shoes 31 40 31 32 37…
The variance of temperatures (Fahrenheit) in Las Vegas, Nev. is 327.84. What is this variance if temp is re-expressed in Celsius? [Hint: Conversion between Fahrenheit and Celsius is a linear transformation: Fahrenheit = Celsius*1.80 + 32, or Celsius = Fahrenheit*(1/1.80) - (32/1.80)]
When a least squares line is fit to the 11 observations in the service time data, we obtain SSE= 210.8204. Calculate s? and s. (Round s2 to 4 decimal places. Round s to 5 decimal places.) s^2 This is a numeric cell, so please enter numbers only.
Use least squares regression to fit polynomials of order 1, 3 and 5 to the data given in table. Compute the correlation coefficient for each fit (Use Gauss elimination with partial pivoting in the solution of linear equation systems). Plot 1st, 3rd, and 5th order polynomial fits and the given discrete data. Comment on which of these curves explain better the variability of given data. I have a solution at second image but i dont understand where did the functions like "y=2.3021x^3+..." come from? I need a detailed description about it. Thank you
A regression and correlation analysis resulted in the following information regarding a dependent variable (y) and an independent variable (x). Σx = 90 Σ(y - )(x - ) = 466 Σy = 170 Σ(x - )2 = 234 n = 10 Σ(y - )2 = 1434 SSE = 505.98 The least squares estimate of the slope or b1 equals a. .923. b. 1.991. c. -1.991. d. -.923.
Given the “data” determined by y = x^3 + (x-1)^2 with x = 0.1, 1.2, 2.3, and 2.9, calculate SSTO, SSR, and R^2. Then recalculate these using x = 0.3, 1, 2.45, and 2.8. Does where you collect your data (i.e., which values of x) appear to impact your interpretation of how good the linear model fits?.

Dioxin Researchers have linked an increase in the inci-dence of breast cancer in Italy to dioxin released by an industrial accident in 1976. The study identified 981women who lived near the site of the accident and were under age 40 at the time. Fifteen of the women had devel-oped breast cancer at an unusually young average age of 45. Medical records showed that they had heightened con-centrations of dioxin in their blood and that each tenfold increase in dioxin level was associated with a doubling ofthe risk of breast cancer.
