A scientist claims that the mean water temperature in the Florida Everglades is greater than 30 °C. . He records water temperatures at the same station over a 61-day period. The temperature is recorded at the same time each day, and the mean is found to be 30.4°C. Assume that standard deviation  = 1.7 C.

Construct a 95% confidence interval for the population mean.

Interpret the interval.

Is the scientist’s claim consistent with the data? Explain. No credit for “YES/NO” answer only.

Find the sample size necessary for a 95% confidence interval with a maximal margin of error of 0.35.

Question 4: An article in Wikipedia claims that the mean body temperature of adults is less than 98.6° F. This goes against everything you’ve ever been taught, so you gather 565 healthy adults and observe a mean body temperature of 98.2°F, with the sample standard deviation of 2.6°F. Test the article’s claim at a 5% level of significance. If the problem is a confidence interval: Show whether the criteria for approximate normality are met. (1 point) Summarize the sample statistics....

Question #1 How hot is the air in the top (crown) of a hot air balloon? Information from Ballooning: The Complete Guide to Riding the Winds, by Wirth and Young (Random House), claims that the air in the crown should be an average of 100°C for a balloon to be in a state of equilibrium. However, the temperature does not need to be exactly 100°C. What is a reasonable and safe range of temperatures? This range may vary with the...

1. A city official claims that the proportion of all commuters who are in favor of an expanded public transportation system is 50%. A newspaper conducts a survey to determine whether this proportion is different from 50%. Out of 225 randomly chosen commuters, the survey finds that 90 of them reply yes when asked if they support an expanded public transportation system. Test the official’s claim at α = 0.05. 2. A survey of 225 randomly chosen commuters are asked...
