Noise and Intelligibility Audiologists study the intelligibility of spoken sentences under different noise levels. Intelligibility, the MRT score, is measured as the percent of a spoken sentence that the listener can decipher at a cesl4ain noise level in decibels (dB). The table shows the results of one such test. (a) Make a scatter plot of the data. (b) Find and graph the regression line. (c) Find the correlation coefficient. Is a linear model appropriate? (d) Use the linear model in put (b) to estimate the intelligibility of a sentence at a 94-dB noise level.
Planetary Velocity The following table gives the mean velocity of planets in their orbits versus their mean distance from the sun. Note that 1AU astronomical unit is the mean distance from Earth to the sun, abut 93 million miles. Planet d=distance AU v=velocity km/sec Mercury 0.39 47.4 Venus 0.72 35.0 Earth 1.00 29.8 Mars 1.52 24.1 Jupiter 5.20 13.1 Saturn 9.58 9.7 Uranus 19.20 6.8 Neptune 30.05 5.4 Astronomers tell us that it is reasonable to model these data with a power function. a Use power regression to express velocity as a power function of distance from the sun. b Plot the data along with the regression equation. c An asteroid orbits at a mean distance of 3AU from the sun. According to the power model you found in part a, what is the mean orbital velocity of the asteroid?

A Logistic Regression model was used for classifying common brushtail possums into their two regions. The outcome variable takes value 1 if the possum was from Victoria and 0 otherwise. We consider five predictors: sex_male (an indicator for a possum being male), head length, skull width, total length, and tail length. A summary table is provided below. Estimate Std. Error Z value Pr(>||I) (Intercept) 33.5095 9.9053 3.38 0.0007 sex_male -1.4207 0.6457 -2.20 0.0278 0.0231 skull_width total_length tail_length -0.2787 0.1226 -2.27 0.5687 0.1322 4.30 0.0000 -1.8057 0.3599 -5.02 0.0000 Suppose we see a brushtail possum at a zoo in the US, and a sign says the possum had been captured in the wild in Australia, but it doesn't say which part of Australia. However, the sign does indicate that the possum is female, its skull is about 53 mm wide, its total length is 93 cm and its tail is 40 cm long. What is the predicted probability that this possum is from Victoria? Choose an option that is…
(a) Compute MSE using the most recent value as the forecast for the next period. What is the forecast for month 8? The MSE, mean squared error, is a measure of forecast accuracy and is the average of the squared forecast errors. Before this can be found, we first need to find the forecast values, forecast error, and squared forecast errors. Forecasts will be made using the most recent values known. There will be no forecast for the first month. The forecast value for month 2 will be the observed value from month 1, so the forecast value for month 2 is The forecast value for month 3 will be the observed value from month This pattern will continue for the rest of the months. 2, so the forecast value for month 3 is Complete the column for the forecast value in the table below.
