Questions13-14: Adult male polar bears are expected to weigh, on average, 370 kg. A polarbear's primary source of food is seals and other marine animals, which they hunt from aplatform of sea ice. Scientists are concerned that global warming is melting these platformsearlier in the year, reducing the time polar bears are able to hunt and forcing them inlandwithout the necessary fat reserves built up to survive summer and fall. The US GeologicalSurvey (USGS) conducted a study in the Southern Beaufort Sea to investigate whether climatechange has appeared to negatively impact the weight of polar bears. Eighty-three adult malepolar bears were captured between March and May of the years 1990 and 2006 and theirweights were recorded. The sample mean weight was 324.6 kg, and the sample standarddeviation was 88.3 kg.13. Use the Theory-Based Inference applet to determine the p-value to investigate whetherclimate change has appeared to negatively impact the weight of polar bears.A. p-value = 0.0468B. p-value = 1C. p-value = 0.05D. p-value = 0.000014. Do these results provide evidence that the true mean weight of polar bears is less than370 kg? And explain.

It is given that Sample size n = 83 Sample mean = 324.6 Sample SD = 88.3 Population mean = 370

Listed below are altitudes (thousands of feet) and outside air temperatures (°F) recorded during a flight. Find the (a) explained variation, (b) unexplained variation, and (c) indicated prediction interval. There is sufficient evidence to support a claim of a linear correlation, so it is reasonable to use the regression equation when making predictions. For the prediction interval, use a 95% confidence level with the altitude of 6327 ft (or 6.327 thousand feet). Altitude Temperature a. Find the explained variation.

Professor Nord stated that the mean score on the final exam from all the years he has been teaching is a 79%. Colby was in his most recent class, and his class’s mean score on the final exam was 82%. Colby decided to run a hypothesis test to determine if the mean score of his class was significantly greater than the mean score of the population. α = .01. What is the mean score of the population? What is the mean score of the sample? Is this test one-tailed or two-tailed? Why?
Before every flight, the pilot must verify that the total weight of the load is less than the maximum allowable load for the aircraft. The aircraft can carry 43 passengers, and a flight has fuel and baggage that allows for a total passenger load of 7,009 lb. The pilot sees that the plane is full and all passengers are men. The aircraft will be overloaded if the mean weight of the passengers is greater than 7,009 lb / 43 =163 lb. What is the probability that the aircraft is overloaded? Should the pilot take any action to correct for an overloaded aircraft? Assume that weights of men are normally distributed with a mean of 182.4 lb and a standard deviation of 38.4.
The Department of Agriculture wants to determine whether the mean yield per acre for a particular variety of soybeans is different this year compared to the historical avg yield of 520 bushels per acre. Thus, the null and alternative hypotheses are Ho: mu = 520 Ha: mu is not = to 520 You set out to conduct a hypothesis test at the 95% level. Mean yields are distributed Normally. You take a sample of 36 different acres. From this sample, you calculate a mean yield of 573 and a std deviation of 24. Do you reject or not-reject the null hypothesis? Group of answer choices Do not reject the null hypothesis. Reject the null hypothesis.
