The average measured verbal IQ (IQV) scores of children is 100. In a sample of 20 children, the average was 86.9. Assume the population is normally distributed, and the population standard deviation is 18.5. If we were to ask for a minimum sample size for a 94% level of confidence, what would be the value for z-sub-c? Round to 2 decimal places. Question 3 options:

You want to obtain a sample to estimate a population mean. Based on previous evidence, you believe the population standard deviation is approximately σ=72.1σ=72.1. You would like to be 99% confident that your estimate is within 2 of the true population mean. How large of a sample size is required?
The nicotine content in cigarettes of a certain brand is normally distributed. The brand advertises that the mean nicotine content of their cigarettes is µ = 1.5, but measurements on a random sample of 100 cigarettes of this brand gave a mean of ?̅= 1.53 and s = 0.95. Is this evidence that the mean nicotine content is actually higher than advertised? 1. State the appropriate null and alternative hypotheses. H0: ? = 1.5 Ha: ? > 1.5 2. Should you use the z or t test? t – do not have sigma 3. Compute the test statistic to test your hypotheses. (report to 2 decimal places) ? = 1.53−1.5 0.95 √100 ⁄ = 0.32 4. Find the appropriate range of p-value for your test. P-value: a. Less than 0.005 b. Between 0.005 and 0.01 c. Between 0.01 and 0.025 d. Between 0.025 and 0.05 e. Greater than 0.05

The director of research and development is testing a new drug. She wants to know if there is evidence at the 0.05 level that the drug stays in the system for more than 357 minutes. For a sample of 19 patients, the mean time the drug stayed in the system was 364 minutes with a standard deviation of 25. Assume the population distribution is approximately normal. Step 1 of 7: State the null and alternative hypotheses Step 2 of 7: Find the value of the test statistic. Round your answer to two decimal places. Step 3 of 7: Specify if the test is one-tailed or two-tailed. Step 4 of 7: Determine the P-value of the test statistic. Round your answer to four decimal places. Step 5 of 7: Identify the value of the level of significance.

Please use the following information to answer question 9a & 9b: A random sample of n = 16 scores is obtained from a population with a mean of µ = 45. After a treatment is administered to the individuals in the sample, the sample mean is found to be x̅ = 49.2. 9a. Assuming that the sample standard deviation is s = 20, calculate r2 (MUST SHOW WORK FOR THIS PROBLEM). Note: You must provide calculations for the t-statistic, in addition to r2. 9b. Calculate Cohen's d to measure the size of the treatment effect (MUST SHOW WORK FOR THIS PROBLEM). Comparing your answers from 8 (a&b) and 9 (a&b), fill in the blank to properly describe how the variability of scores in the sample influence the measures of effect size. (8. A random sample of n = 16 scores is obtained from a population with a mean of µ = 45. After a treatment is administered to the individuals in the sample, the sample mean is found to be x̅ = 49.2. 9.

Our environment is very sensitive to the amount of ozone in the upper atmosphere. The level of ozone normally found is 4.8 parts/million (ppm). A researcher believes that the current ozone level is at an insufficient level. The mean of 6 samples is 4.6 pm with a standard deviation of 1.0 Does the data support the claim at the 0.05 level? Assume the population distribution is approximately normal. Step 4 of 5 : Determine the decision rule for rejecting the null hypothesis. Round your answer to three decimal places.
Use the following information to complete steps (a) through (d) below. A random sample of size n, = 31 results in a sample mean of 125.3 and a sample standard deviation of 8.5. An independent sample of size n, = 50 results in a sample mean of 131.8 and sample standard deviation of 7.3. Does this constitute sufficient evidence to conclude that the population means differ at the g = 0.05 level of significance? O A. Ahypothesis test regarding the difference of two means using a matched-pairs design. O B. Ahypothesis test regarding the difference between two population proportions from independent samples. O C.
