Find and interpret the p-value for this test......The p-value for this test is(Round to three decimal places as needed.)Interpret the result. Select the correct choice below and fill in the answer box to complete your choice.(Round to three decimal places as needed.)O A. The probability (assuming that Ho is true) of observing a value of the test statistic that is at least as contradictory to thenull hypothesis is.B. The probability (assuming that H, is true) of observing a value of the test statistic that is at most as contradictory to thenull hypothesis isO C. The probability (assuming that H, is true) of observing a value of the test statistic that is equal to the null hypothesis is

I’m stuck on how to do this problem for stats.
A sample of 314 patients between 38 and 82 were given a drug intended to reduce their level of cholesterol. The results were the mean reduction in cholesterol of 0.94 millimole per liter. Assume the population standard deviation is σ = 0.18. Construct a 98% C.I.
Need step by step directions to determine the P-value. Thanks
In the entire population of a certain type of tree, the mean height of the trees is μ = 168.8 ft and the standard deviation is σ = 43.6 ft. You collect a random sample of n=22 trees. The distribution of these sample means is shown below. Each tick mark on the horizontal axis is a distance of one more standard error. Complete the indicated boxes, correct to two decimal places. mean of distribution=168.8 standard error=9.30 Note: The left box is 2 standard errors below the mean. The middle box is the mean. The right box is 2 standard errors above the mean.
This assignment is worth 1 points. The extra point will be added to your overall course grade. For example: if you receive an 88% in the course you can receive up to 1 point giving you a new score of 89%. The following rubric will be used. 0.25 point for drawing the normal distribution curve with the mean value labeled on the curve and the appropriate area shaded. 0.25 point for determining the value of the standard deviation of the sample mean. 0.5 point for finding the correct probability. All work must be shown in order to receive any credit. Please upload your completed assignment here. The length of time taken on the SAT for a group of students is normally distributed with a mean of 2.5 hours and a standard deviation of 0.25 hours. A sample size of n = 60 is drawn randomly from the population. Find the probability that the sample mean is between two hours and three hours.
The manufacturer claims that your new car gets 24 mpg on the highway. You suspect that the mpg is less for your car. The 44 trips on the highway that you took averaged 22.3 mpg and the standard deviation for these 44 trips was 4.2 mpg. What can be concluded at the αα = 0.05 level of significance? For this study, we should use (t-test for population mean, z-test for population proportion) The null and alternative hypotheses would be: H0: (symbol) (symbol) ____ H1: (symbol) (symbol) ____ The test statistic (?,t,z) = (please show your answer to 3 decimal places.) The p-value = (Please show your answer to 4 decimal places.) The p-value is (?, less than or equal to, more than) αα Based on this, we should (accept, reject, fail to reject) the null hypothesis. Thus, the final conclusion is that ... The data suggest that the sample mean is not significantly less than 24 at αα = 0.05, so there is statistically insignificant evidence to conclude…
A manufacturer of bolts has a quality control policy that requires it to destroy any boits that are more than 4 standard deviations from the mean The quality control engineer knows that the bots coming off the assembly line have moan length of 9 cm with a standard deviation of 0.05 cm.

A bolt will be destroyed if the length is less than OB A bolt will be destroyed if the length is less than OC. A bolt will be destroyed if the length is greater than cm. cm or greater than cm D.

How much money on average does a fan of professional football spend on food at a single football game? This question was posed to 71 randomly selected football fans. The sample results provided a sample mean and standard deviation of 15.15 euro and 2.6 euro, respectively. Estimate the value of the population mean, μ, the mean amount of money football fans spend on food at a single game. Fill in the blanks in the following: • An estimate of the population mean is 15.15 • The standard error is • The distribution is normal (examples: normal/t12/chisquare4/F5,6). For a 90% confidence interval the distributional cut-off is It is quite likely that the true mean amount of money football fans spend on food at a single game is between with 90% confidence. and
