Assume that the readings on the thermometers are normally distributed with a mean of 0° and standard deviation of 1.00°C. Assume 2.5​% of the thermometers are rejected because they have readings that are too high and another 2.5​% are rejected because they have readings that are too low. Draw a sketch and find the two readings that are cutoff values separating the rejected thermometers from the others. The cutoff values are ____ degrees Round to 2 decimal places

Mason earned a score of 226 on Exam A that had a mean of 250 and a standard deviation of 40. He is about to take Exam B that has a mean of 550 and a standard deviation of 25. How well must Mason score on Exam B in order to do equivalently well as he did on Exam A? Assume that scores on each exam are normally distributed.

Suppose babies born after a gestation period of 32 to 35 weeks have a mean weight of 2500 grams and a standard deviation of 800 grams while babies born after a gestation period of 40 weeks have a mean weight of 3000 grams and a standard deviation of 385 grams. If a 32​-week gestation period baby weighs 2650 grams and a 41​-week gestation period baby weighs 3150 ​grams, find the corresponding​ z-scores. Which baby weighs more relative to the gestation​ period? Find the corresponding​ z-scores. Which baby weighs relatively more​? Select the correct choice below and fill in the answer boxes to complete your choice. ​(Round to two decimal places as​ needed.)   A. The baby born in week 41 weighs relatively more since its​ z-score, nothing​, is smaller than the​ z-score of nothing for the baby born in week 32.   B. The baby born in week 32 weighs relatively more since its​ z-score, nothing​, is smaller than the​ z-score of nothing for the baby born in week 41.   C. The…

Suppose babies born after a gestation period of 32 to 35 weeks have a mean weight of 2500 grams and a standard deviation of 700 grams while babies born after a gestation period of 40 weeks have a mean weight of 2700 grams and a standard deviation of 340 grams. If a 34​-week gestation period baby weighs 2275 grams and a 40​-week gestation period baby weighs 2475 ​grams, find the corresponding​ z-scores. Which baby weighs less relative to the gestation​ period?

The brain volumes (cm) of 20 brains have a mean of 1098.4 cm° and a standard deviation of 120.1 cm. Use the given standard deviation and the range rule of thumb are significantly low or significantly high. For such data, would a brain volume of 1328.6 cm° be significantly high? identify the limits separating values that Significantly low values are cm or lower. (Type an integer or a decimal. Do not round.)

The average labor charge for automobile mechanics is OMR 69 per hour. The standard deviation is OMR 18. Find the minimum percentage of data values that will fall within the range of OMR 68 to OMR 80. Use Chebyshev's theorem. SHOW ALL THE WORKINGS, FORMULA etc.

For a certain type of computers, the length of time between charges of the battery is normally distributed with a mean of 62 hours and a standard deviation of 11 hours. John owns one of these computers and wants to know the number of hours when the computer would have 12%  of its battery life left. Sketch the region in question. Write a sentence describing what your answer represents about the problem's specefics.

Assume that the readings on the thermometers are normally distributed with a mean of 0° and standard deviation of 1.00°C. Assume 2.1​% of the thermometers are rejected because they have readings that are too high and another 2.1​% are rejected because they have readings that are too low. Draw a sketch and find the two readings that are cutoff values separating the rejected thermometers from the others.

Suppose the police have set up automatic speed surveillance on a street in an area. During one week they get 987 measurements. The average in the data set is 50,7 kh/h, with a standard deviation of 3,2 km/h.   Calculate the z-value for an observation with the value 53,8 km/h.
