IQ scores are normally distributed with standard deviation o= 15 points. Youwish to determine the mean IQ of all students in Matiyaga National High School bytaking a random sample of 16 students.16. The general weighted average (GWA) of the Grade 11 applicants for admissionin ASHS over the past 6 years has been consistently μ = 92.78. This year a sampledata of the applicant's GWA are 98, 89, 92, 95, 90, 97 and 93.17. This distribution is used to determine the probability of an event by transformingthe mean of the sample to an approximately standard normal variable if the populationvariance is known and sample size is greater than 30.a. t-Distributionc.

The correct size of a nickel is 21.21 millimeters. Based on that, the data can be summarized into the following table: Too Small Too Large Total Low Income 12 28 40 High Income 25 10 35 Total 37 38 75 Based on this data: (give your answers to parts a-c as fractions, or decimals to at least 3 decimal places. Give your to part d as a whole number.)a) The proportion of all children that drew the nickel too small is: Assume that this proportion is true for ALL children (e.g. that this proportion applies to any group of children), and that the remainder of the questions in this section apply to selections from the population of ALL children.b) If 6 children are chosen, the probability that exactly 2 would draw the nickel too small is: c) If 6 children are chosen at random, the probability that at least one would draw the nickel too small is: d) If 90 children are chosen at random, it would be unusual if more than drew the nickel too small

6. Setup: JP was curious about the sodium content of organic cornflakes. To investigate this, twenty 300-gram boxes of organic cornflakes were obtained and the sodium content was measured. The data (in milligrams) are as follows: 131.1, 130.7, 130.9, 129.5, 129.6, 128.8, 130.7, 128.3, 128.2, 129.7, 130.1, 129.3, 128.7, 129.0, 129.4, 130.4, 129.5, 130.1, 129.8, 130.0 Task: Perform a hypothesis test using R to determine if you can support a claim that the mean sodium content of this brand of cornflakes differs from 130 milligrams? Use a = 0.08 to make your decision. R Output: Upon running your analysis in R, you obtain the following results: One Sample t-test data: corn = 0.1121 t = -1.6659, df = alternative hypothesis: true mean is not equal to 130 19, р-value 92 percent confidence interval: 129.3458 130.0342 sample estimates: mean of x 129.69 Questions: (a) State the hypotheses used in performing this test.
