3. The distribution of test scores in a class is unimodal and symmetric with a mean of 80 pts and a standard deviation of 7pts. Based on the information, Adam estimated that his score is higher than approximately 97.5% of the students in class. What score did Adam receive? Explain.
My question is: Task 3. Report the mean, standard deviation, skewness, and kurtosis for each of the three prior activity levels. Based on these statistics do you think the assumptions of constant variance and normality of errors are appropriate ? Below Average (Mean = 33.42, SD - 5.477, Skewness = -1.127, Kurtosis = -0.395) Average (Mean = 32, SD - 3.464, Skewness = 0.902, Kurtosis = -0.208) Above Average (Mean = 24, SD - 4.427, Skewness = 1.452, Kurtosis = 1.888) thank you
1. Depression scores (1-100) for young women (20-40 years old) are assumed to be normally distributed with a mean of 75.5 within the population. A sample of 26 women were recruited to have their depression scores recorded and the mean score was 82, with a standard deviation of 12. Researchers want to know if the sample data reflects a population with mean score of 75.5. Using a significance level of 0.01, answer the following questions. (a) What statistical test should the researchers conduct? Why? Explain your answer. (b) State the hypotheses for this scenario. (c) Conduct a hypothesis test based on question 1(a) to determine what the researcher should conclude from this study. Give your answer to two decimal places. (d) Suppose you obtained several random samples each with n = 100 women and each time you obtained their depression scores. Is it reasonable to assume that the sample means of these samples xx are approximately Normally distributed even though the population distribution…
1. A simple random sample of 21 people with early-onset dementia have the mean age at diagnosis of 52.3 years and the standard deviation of 6.5 years. Assume that ages at the diagnosis of dementia are normally distributed. We are to perform a hypotheses test to determine whether mean age at diagnosis of all people with early-onset dementia is different from 55 years. a. If one percent significance level is used then: i. RR = {t ≥ 2.528} ii. RR = {t ≤ −2.528} iii. RR={t≤−2.528}∪{t≥2.528} iv. RR = {t ≤ −2.845} v. RR = {t ≥ 2.845} vi. RR = {t ≤ −2.845}∪{t ≥ 2.845} b. At one percent significance level, we can conclude that mean age at diagnosis of all people with early-onset dementia is i. Is equal to 55 years 2. Is equal to 52.3 years 3. Is not equal to 52.3 years 4. Is not equal to 55 years

. A process that cuts lengths of metal with high precision has historically produced metal rods with length that is normally distributed and with a mean of 800 millimetres (mm). Management at the factory is concerned that after an overhaul of the machine the mean length of the rods being produced could differ from the required 800 mm. If it is found that the rods are not being produced to specifications then the machine will have to be stopped for readjustment, with a consequent loss of production. The production line manager tasked with investigating the issue finds that a (random) sample of 25 rods yielded a mean length of 806 mm and a sample standard deviation of 10 mm. i. The mean of the sample is clearly not the required 800 mm. Say why this is not enough information in itself to say if the machine is operating correctly or not. ii. State the null and alternative hypotheses for this situation.
