Suppose X ~ N (2, 3). What value of x has a z-score of -0.69? Suppose X ~ N(4, 2). What value of x is two standard deviations to the right of the mean? I need help solving these two problems. If you could explain that would help understand the steps of solving these types of problems. Thank you for your time
Suppose the scores of students on an exam are normally distributed with a mean of 376 and a standard deviation of 30. Then approximately 95% of the exam scores lie between the integers _ & _ such that the mean is half way between these two integers. I know the answers are 316 and 436. But I don't know how they got them. I cannot use excel and so I need help to solve this by hand. Thanks so much in advance!
The population of college students using “normal shoes” is able to complete a particular racecourse in an average of 250 seconds. The standard deviation for this population is 20 seconds and the population is normally distributed. A random sample of 28 college students is given a special pair of new shoes and asked to run the course. The average “race time” for this group is 243 seconds. assume now that the designer of the shoes states that his shoes should improve the times of the user (less time to finish the race). State the hypotheses involved. determine if the hypothesis test is one tailed or two tailed Give the Z scores associated with cut-off points for .01, .05, and .10 (1%, 5%, and 10% respectively). Calculate the Z score for this problem. Based on a cut-off point or alpha level of .05 (5%), what decision would you make about your hypotheses? Explain this decision. Make conclusions regarding the specifics of this study.
An experiment is conducted to compare the maximum load capacity in tons (the maximum weight that can be tolerated without breaking) for two alloys A and B It is Kknown that the two standard deviations in load capacity are equal at 7 tons each. The experiment is conducted on 50 specimens of each alloy (A and B) and the results are X = 75.8. X = 71.8, and X-X=4. The manufacturers of alloy A are convinced that this evidence shows conclusively that Hug and strongly supports the claim that their alloy is superior. Manufacturers of alloy 8 claim that the experiment could easily have given X-X 4 even if the two population means are equal. Complete parts (a) and (b) below.

Q2. Assume we have two populations represent the mercury contamination (g/Km3) in two different European cities. The mean of mercury contamination in the first city is 50 g/Km3 with standard deviation of 1O, and mean of mercury contamination in the second city is 40 g/Km3 with standard deviation of 8 g/Km3. If a sample of n=9 is taken form first city and a sample of n=16 is taken form second city, what is the probability that the difference between these two sample means is less than 9 g/Km3? 0.0614 0.0359 0.3985 0.0992 0.6015

While, mean durability of artificial lamp B is 820 hours and its standard deviation is 60 hours. Find the probbality of 35 artificial lamp A will have mean durabilirty at least 25 hours more than 45 artificial lamp B.
A local chess club claims that the length of time to play a game has a standard deviation of less than 11 minutes. Write sentences describing type I and type Il errors for a hypothesis test of this claim. A type I error will occur if the actual standard deviation of the length of time to play a game is V 11 minutes, but you the null hypothesis, A type Il error will occur if the actual standard deviation of the length of time to play a game is 11 minutes, but you the null hypothesis,
