Your firm manufactures medicine which is dispensed into bottles. The mean fill level for the medicine bottles is supposed to be 200 ml. You take a random sample of 13 bottles and find the following fill levels (in milliliters): 195, 195, 200, 198, 204, 195, 201, 199, 204, 195, 196, 202, 199 Assume that the fill levels are Normally distributed in the entire population. Assume that the population standard deviation for all fill levels of medicine bottles σ is unknown. Construct and interpret 90% confidence interval for the mean fill level μ of medicine bottle. Write a statement which correctly states the meaning of this interval in the context of the problem. Round all final answers to 2 decimal places, if needed. (a) The average fill level for the sample of 13 medicine bottles is (b) We are 90% confident that the mean fill level of medicine bottles μ is between and (milliliters)
Students in the senior capstone course (N=36) at Central State University took the Political Science subtest developed by the National Board Testing Association. The test is a 75-item, multiple choice test covering all areas of political science. The national norms for the test show a mean of 50. The mean for the students in the capstone course was 55, with a standard deviation of 15. Did the students at CSU score significantly higher than the national average? State your null and alternative hypothesis Is this a one-or-two tailed hypothesis? Explain thoroughly. Calculate the appropriate statistical test. Can you reject the null hypothesis? Why or why not?
The mean voltage and standard deviation of 10 batteries from each manufacturer were measured. The results are summarized in the following table. Manufacturer ASample mean voltage(millivolts): 191Sample standard deviation (millivolts) 1 Manufacturer BSample mean voltage(millivolts): 187Sample standard deviation (millivolts) 4 What type of hypothesis test should be performed? Unpaired t-testLeft-tailed z-testPaired t-testTwo-tailed z-test What is the test statistic? What is the number of degrees of freedom? Does sufficient evidence exist to support the claim that the voltage of the batteries made by the two manufacturers is different at the α = 0.05 significance level? A) YesB) No
Do wearable devices that monitor diet and physical activity help people lose weight? Researchers had 237 subjects, already involved in a program of diet and exercise, use wearable technology for 24 months. They measured their weight (in kilograms) before using the technology and 24 months after using the technology. (a) Explain why the proper procedure to compare the mean weight before using the wearable technology and 24 months after using the wearable technology is a matched pairs t test. Choose the correct explanation. A person's weight before and after wearing the device would not be independent; thus, the data from this before and after study should be analyzed using a matched pairs t test. O A person's weight before and after wearing the device would be independent; thus, the data from this before and after study should be analyzed using a matched pairs t test.

Methyl t-butyl ether (MTBE) is an organic water contaminant that often results from gasoline spills. The level of MTBE (in parts per billion) was measured for a sample of 12 well sites located near the ship channel during a recent spilI. The data are: 150, 376, 38, 12, 11, 134, 12, 251, 63, 8, 13, 107. (a) Find the sample mean and the sample standard deviation. (b) Construct and interpret a 91.85% and 98.15% confidence interval for the population mean by using the following equations: B, = x – t - - and By = x +t N sample N sample (c) Which confidence interval is wider and why?
Steel rods manufactured in a plant must be a minimum of 2 metres in length in order to pass through an inspection procedure. Steel rods with lengths that are normally distributed, with a mean of 2.1 metres and a standard deviation of 0.1 metres, are produced during the manufacturing process. A random sample of 25 steel rods is chosen, and their lengths are measured using a tape measure. i. Decide on the appropriate distribution of the sample mean of the 25 steel rods in the sample using the appropriate distribution formula. ii. Calculate the probability that the sample mean of steel rods that meet the minimum length requirement is the same as the mean of the entire sample. iii. For example, if the observed sample mean length of steel rods is 2.15, calculate the 98% two-sided confidence interval for the true mean length of the manufacturing process, assuming that it is not known.
Independent random samples of households in the 5 U.S. regions yielded the data on last year’s energy consumption(Kilowatts). At the 5% significance level, do the data provides sufficient evidence to conclude that a difference exists in last year’s mean energy consumption by households among the 5 U.S. regions?

Out of the attacks that took place in 2018, was the mean number of fatalities greater in bombing/explosion attack types than in all other attack types? i need to come up with a correct statistical test to test this research based on the data that i gathered i have this. i gathered a sample of 80 ATTACKS. 33 of the attacks were sucessful attacks using BOMBINGS/EXPLOSIONS 35 of them were sucessful attackd by all other types of attacks need a way to use a statistical research method
Because of low results, the school principal decided to change the teacher. The last test with the previous teacher, which was written by 18 people, showed an average of 58 with deviation of 12. A month later, a new teacher conducts a similar test that is written by 19 people, with an average score of 60, and the deviation of 14. Calculate the t-test statistic. Select answer from the options below A)The t-test statistic is -0.467 . B)The t-test statistic is 0.828. C)The t-test statistic is 0.467. D)The t-test statistic is -1.688 .
