#/Skip/8It is commonly believed that the mean body temperature of a healthy adult is 98.6° F. You are not entirelyconvinced. You believe that it is not 98.6° F. You collected data using 52 healthy people and found thatthey had a mean body temperature of 98.25° F with a standard deviation of 1,12° F. Use a 0.05significance level to test the claim that the mean body temperature of a healthy adult is not 98.6°F.a) Identify the null and alternative hypotheses?Ho: ? vHa: ? Vb) What type of hypothesis test should you conduct (left-, right-, or two-tailed)?O left-tailedOright-tailedO two-tailedc) Identify the appropriate significance level.d) Calculate your test statistic, (Round your final answer to two decimal places.e) Calculate your p-value. (Round your final answer to four decimal places.f) Do you reject the null hypothesis?O We reject the null hypothesis, sipce the p-value is less than the significance level.O We reject the null hypothesis, since the p-value is not less than the significance level.O We fail to reject the null hypothesis, since the p-value is less than the significance level.O We fail to reject the null hypothesis, since the p-value is not less than the significance level.g) Select the statement below that best represents the conclusion that can be made.O There is sufficient evidence to warrant rejection of the claim that the mean body temperature of ahealthy adult is not 98.6 F,O There is not sufficient evidence to warrant rejection of the claim that the mean body temperature ofa healthy adult is not 98.6° F.O The sample data support the claim that the mean body temperature of a healthy adult is not 98.6° FO There is not sufficient sample evidence to support the claim that the mean body.temperature of ahealthy adult is not 98.6° F,

An instructor at a private college claim that the students enrolled in her school have an IQ of average intelligence. If there are a total of 40 students’ IQ scores as sample and have a mean of 106. Is the instructor’s claim true? Mean population IQ is 97 with a standard deviation of 12. Use alpha level of 0.05.
Consider a set of data in which the sample mean is 30.230.2 and the sample standard deviation is 7.87.8. Calculate the z-score given that x=31.4x=31.4. Round your answer to two decimal places.
An environmental researcher took 30 water samples from different areas of a lake. He measured the pH level of each water sample. The standard deviation for the 30 pH levels was about 1.4.What is the best interpretation of the standard deviation? The pH level of a typical water sample was about 1.4 units from the mean on average. The difference between the minimum and maximum pH levels was about 1.4 units. The entire lake had a pH level that was about 1.4 units. The pH level of any given water sample was about 1.4 units from the mean. - this one is wrong
A successful basketball player has a height of 6 feet 11 inches, or 211 cm. Based on statistics from a data set, his height converts to the z score of 5.17. How many standard deviations is his height above the mean?
An article in a local town newspaper discusses the results of state test scores in their town. The reporter headlines, "The students in this town don't have the necessary skills. The overall student population is less than what is reported at the state level" The state test says that a score of 261 or higher on its test reflects the student has the skills needed to graduate. A local town newspaper conducted a random sample of 200 students and found the mean to be 257 and a standard deviation of 41 points. a. State the null (H0) and alternative (Ha) hypotheses. b. Give the standard score for the data. c. Find the P-value for this significance test. e. Sketch your results on the standard Normal distribution f. Summarize the conclusion in the context of this problem.
In a recent year, Washington State public school students taking a mathematics assessment test had a mean score of 276.1 and a standard deviation of 34.4. A random sample of 64 students is drawn from this population. Identify the mean and standard deviation of the sample mean scores. 2. Find the probability that the sample mean score is at least 285.
Pyramid Lake is on the Paiute Indian Reservation in Nevada. The lake is famous for cutthroat trout. Suppose a friend tells you that the average length of trout caught in Pyramid Lake is ? = 19 inches. However, a survey reported that of a random sample of 51 fish caught, the mean length was x = 18.6 inches, with estimated standard deviation s = 3.5 inches. Do these data indicate that the average length of a trout caught in Pyramid Lake is less than ? = 19 inches? Use ? = 0.05. (a)What is the level of significance? =__ State the null and alternate hypotheses. A-H0: ? = 19 in; H1: ? ≠ 19 in B-H0: ? < 19 in; H1: ? = 19 in C-H0: ? = 19 in; H1: ? < 19 in D-H0: ? = 19 in; H1: ? > 19 in E-H0: ? > 19 in; H1: ? = 19 in (b)What sampling distribution will you use? Explain the rationale for your choice of sampling distribution. A-The Student's t, since the sample size is large and ? is known. B-The standard normal, since the sample size is large and ? is known. C-The…
