| 75°F Cloudy Hypothesis test for the population mean: t test A college professor claims that the entering class this year appears to be smarter than entering classes from previous years. He tests a random sample of 20 of this year's entering students and finds that their mean IQ score is 117, with standard deviation of 15. The college records indicate that the mean IQ score for entering students from previous years is 113. If we assume that the IQ scores of this year's entering class are normally distributed, is there enough evidence to conclude, at the 0.05 level of significance, that the mean IQ score, μ, of this year's class is greater than that of previous years? Perform a one-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places and round your answers as specified in the table. (If necessary, consult a list of formulas.) (a) State the null hypothesis Ho and the alternative hypothesis H₁. H₁ : μ = 113 H₁ :μ > 113 (b)…
55°F Clear Heights were measured for a random sample of 15 plants grown while being treated with a particular nutrient. The sample mean and sample standard deviation of those height measurements were 50 centimeters and 12 centimeters, respectively. Assume that the population of heights of treated plants is normally distributed with mean u. Based on the sample, can it be concluded that μ is different from 42 centimeters? Use the 0.10 level of significance. Perform a two-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places and round your answers as specified in the table. (If necessary, consult a list of formulas.)

Medical School Applications A medical college dean read that the average number of applications a potential medical school student sends is 7.7. She thinks that the mean is lower than 7.7. So she selects a random sample of 28 applicants and asks each how many medical schools they applied to. The mean of the sample is 6.8. The population standard deviation is 2.5 . Test her claim at α=0.10. Assume that the variable is normally distributed. Use the P -value method with tables.

A sample of 14 small bags of the same brand of candies was selected. Assume that the population distribution of bag weights is normal. The weight of each bag was then recorded. The mean weight was 2 ounces with a standard deviation of 0.12 ounces. The population standard deviation is known to be 0.1 ounce. x = σ = sx = n = n − 1 =

Data from a state indicate that scores on the SAT test are normally distributed with a mean of 994 and a standard deviation of 204. Scores on the ACT test are normally distributed with a mean of 20 and a standard deviation of 5.1. It is assumed that the two tests measure the same aptitude, but use different scales.If a student gets an SAT score that is the 77 percentile, find the actual SAT score. Round answer to a whole number. SAT score = What would be the equivalent ACT score for this student? Round answer to 1 decimal place. ACT score = If a student gets an SAT score of 1280, find the equivalent ACT score. Round answer to 1 decimal place. ACT score =
Assume that adults have IQ scores that are normally distributed with a mean of 95.2, and a standard deviation of 22.2 Find the first quartile Q1, which is the IQ score separating the bottom 25% from the top 75%. Can you please provide step by step using the T1-84 plus calculator. I keep getting stuck on locating the z-score. I know the first Q is .25 If you use the formula, please provide the actual figures including a picture- so I have a well-rounded answer to this question. Thank you

Calcium levels in people are normally distributed with a mean of 9.7 mgdL and a standard deviation of 0.5 mgdL . Individuals with calcium levels in the bottom 10% of the population are considered to have low calcium levels. Find the calcium level that is the borderline between low calcium levels and those not considered low. Carry your intermediate computations to at least four decimal places. Round your answer to one decimal place.
