A laboratory claims that the mean sodium level, u, of a healthy adult is 141 mEq per liter of blood. To test this claim, a random sample of 48 adult patients is evaluated. The mean sodlum level for the sample is 136 mEq per liter of blood. It is known that the population standard devlation of adult sodilum levels is 13 mEq. Assume that the population is normally distributed. Can we conclude, at the 0.05 level of significance, that the population mean adult sodium level differs from that claimed by the laboratory? Perform a two-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places, and round your responses as specified below. (If necessary, consult a list of formulas.)

A soft drink dispensing machine is said to be out of control if the variance of the contents exceeds 1.15 deciliters. If a random sample of 25 drinks from this machine has a variance of 2.03 deciliters, does this indicate at a significance level of 0.05 that the machine is out of control? Assume that the contents are approximately normally distributed. Note:The exercise in the image is in Spanish, to make the exercise more understandable.
A snack food manufacturer estimates that the variance of the number of grams of carbohydrates in servings of its tortilla chips is 1.141.14. A dietician is asked to test this claim and finds that a random sample of 2424 servings has a variance of 0.950.95. At alpha equals 0.10α=0.10, is there enough evidence to reject the manufacturer's claim? Assume the population is normally distributed.
The capacity of a brand of pipette may be modelled by a normal distribution, and it is claimed that the population mean capacity is 5 millilitres. A random sample of 10 pipettes of this brand is selected, and the capacity of each measured, giving a sample mean of 4.9 millilitres and a sample standard deviation of 0.2 millilitres. Perform a hypothesis test, at a 10% level of significance, to investigate whether or not the population mean capacity of pipettes of this brand is different from 5 millilitres.
An auto manufacturer claims that the variance of the gas mileage in a model of a hybrid vehicle is 0.16. A random sample of 30 vehicles has a variance of 0.26. At alpha = 0.05, is there enough evidence to reject the claim? Assume the population is normally distributed.
A snack food manufacturer estimates that the variance of the number of grams of carbohydrates in servings of its tortilla chips is 1.34. A dietician is asked to test this claim and finds that a random sample of 16 servings has a variance of 1.22. At α=0.05, is there enough evidence to reject the manufacturer's claim? Assume the population is normally distributed. Complete parts (a) through (e) below.
A person read that the average number of hours and adult sleeps on Friday night to Saturday morning was 7.3 hours. The researcher feels that college students do not sleep 7.3 hours on average. The researcher randomly selected 17 students and found that on average they slept 8.5 hours. The standard deviation of the sample is 1.4 hours. At (alpha) = 0.01, is there enough evidence to say that college students do not sleep 7.3 hours on average? Assume that the population is approximately normally distributed. Use the critical value method and tables. A. State the hypotheses and identify the claim with the correct hypothesis. B. Find the critical value(s). C. Compute the test value. D. Make the decision. E. Summarize the results.
A scientist claims that pneumonia causes weight loss in mice. The table attached here shows the weights(in grams) of six mice before infection and two days after infection. At α = 0.01, is there enough evidence to support the scientist’s claim? Assume the samples are random anddependent, and the population is normally distributed.
