Starting engineers in the Philippines earned an average annual salary of P282,000. For the same year, a survey was conducted of 24 Filipino registered engineers to determine if the annual salary is lower than P272,000 for Filipino engineers. The sample average was P408,000 with a sample standard deviation of P274,342. Use a = 0.1 in conducting a hypothesis test.

Suppose Michigan State University's Collegiate Employment Institute found that starting salaries for recipients of bachelor's degrees in business was $50,032 in 2017. The results for a sample of 100 business majors receiving a bachelor's degree in 2018 showed a mean starting salary of $51,279 with a sample standard deviation of $5,200. Conduct a hypothesis test to determine whether the mean starting salary for business majors in 2018 is greater than the mean starting salary in 2017. Use ? = 0.01 as the level of significance. State the null and alternative hypotheses. (Enter != for ≠ as needed.) H0: Ha: Find the value of the test statistic. (Round your answer to three decimal places.) Find the p-value. (Round your answer to four decimal places.) p-value = State your conclusion. Reject H0. There is insufficient evidence to conclude that the mean starting salary for business majors has increased in 2018. Reject H0. There is sufficient evidence to conclude that…
A study was conducted on the average commuting distance of students at College. The study found that the first sample of thirty students has an average commute of 23.1 miles with a sample standard deviation of 12.47 miles. The commuting mileages for a second sample of 30 students are below. a) Find the mean, median and mode for the second sample of students. b) Find the range, variance and standard deviation for the second sample students. c)

The international surfing association interested in determining the number of potential locations for competitions. They have requirements of at least 25 surfable waves per hour during peak surf hours. To find acceptable locations, they had members all over the world submit data from their local beach. The locations had a mean of 32 waves per hour and a standard deviation of 4 waves per hour. What percentage of beaches meet the requirement to be selected by the ISA?

Systolic blood pressure levels above 120 mm Hg are considered to be high. For the 100 systolic blood pressure levels listed in the accompanying data set, the mean is 123.52000 mm Hg and the standard deviation is 16.93510 mm Hg. Assume that a simple random sample has been selected. Use a 0.01 significance level to test the claim that the sample is from a population with a mean greater than 120 mm Hg. Click the icon to view the data set of systolic blood pressure levels. Identify the null and alternative hypotheses. Ho: H;: (Type integers or decimals. Do not round.) Identify the test statistic. (Round to two decimal places as needed.) Identify the P-value. (Round to three decimal places as needed.) State the conclusion about the null hypothesis, as well as the final conclusion that addresses the original claim. the null hypothesis.

The average credit card debt for a recent year was $8,776. Five years earlier the average credit card debt was $8,189. Assume sample sizes of 32 were used and the population standard deviations of both samples were $690. Is there evidence to conclude that the average credit card debt has increased?
For team A, the average number of goals scored per match was 2 with standard deviation (SD) of 1.09 goals. For team B, the average number of goals scored per match was 2.5 with standard deviation (SD) of 1.25 goals. Find which team may be considered more consistent?
Salma recently switched her primary doctor to one specializing in caring for elderly patients. On her new doctor's website, it says that the mean systolic blood pressure among elderly females is 115 millimeters of mercury (mmHg). Salma believes the value is actually higher. She bases her belief on a recently reported study of 21 randomly selected, elderly females. The sample mean systolic blood pressure was 118 mmH, and the sample standard deviation was 21 mmHg. Assume that the systolic blood pressures of elderly females are approximately normally distributed. Based on the study, at the 0.10 level of significance, can it be concluded that y, the population mean systolic blood pressure among elderly females, is greater than 115 mmHg? Perform a one-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places. (If necessary, consult a list of formulas.)
The mean height of students in Negron’s Fall statistics classes is 65.6 inches with a standard deviation 3.89 inches. Sketch the distribution of heights.

Christin ently switched her primary doctor to one specializing in caring for elderly patients. On her new doctor's website, it says that the mean systolic blood pressure among elderly females is 115 millimeters of mercury (mmHg). Christine believes the value is actually higher. She bases her belief on a recently reported study of 14 randomly selected, elderly females. The sample mean systolic blood pressure was 129 mmHg, and the sample standard deviation was 22 Español mmHg. Assume that the systolic blood pressures of elderly females are approximately normally distributed. Based on the study, at the 0.05 level of significance, can it be concluded that u, the population mean systolic blood pressure among elderly females, is greater than 115 mmHg?
