4. An engineer selects 8 components at random and determine the mean measures their strengths to be 74, it is reported that the average strength of the components is between 72.3 and 75.7 with 98% confidence. What is the sample standard deviation of the component strengths?

For all adult women in the US, the diastolic blood pressure is normally distributed with mean 76 mm Hg and standard deviation 12 mm Hg. A physician has data on 16 randomly selected adult US women. There is a 10 % chance that any other person collecting data on 16 randomly selected adult US women will get an average diastolic blood pressure higher than the average diastolic blood pressure for the physician’s sample. What is the average diastolic blood pressure for the physician’s sample? 92.56 72.16 59.44 79.84 Cannot find because we do not know the average blood pressure values for the other samples
Determine the sample size required to estimate the mean score on a standardized test within 4 points of the true mean with 95 % confidence. Assume that s=15 based on earlier studies.
The mean number of english courses taken in two-year time period by male and female college students is believed to be about the same. An experiment is conducted and data are collected from 29 males and 16 females. The males took an average of 3 english courses with a standard deviation of 0.8. The females took an average of four english courses with a standard deviation of 1.0. Are the means statistically the same?
A survey found that women's heights are normally distributed with mean 62.3 inches and standard deviation 2.2 inches. Most of the live characters employed at an amusement park have height requirements of at least 68 inches Find the percentage of women meeting the height requirement?
You are a teacher at a gifted school, and you feel that the newest class of students is even brighter than usual. The mean IQ at your school is 127, and the mean IQ of this new class is 134. In total, there are 32 students in this new class. Also, the standard deviation of the school’s IQ is 8. Use the eight steps to test whether this new class of students is significantly more intelligent than the school’s student body overall.
what is the sample size if the standard deviation is 8 and margin error is 3 at 99%
Find the sample size required to estimate the mean IQ of all college students. Assume we want a 90 per cent confidence level that the sample mean is within 2 IQ points of the true population mean. Also assume that the population standard deviation is 15 IQ points.
Ages of pennies have a mean of 13.13 years and standard deviation of 8.76 years. Suppose we take a sample of 150 pennies from a bank (one roll has 50 cents). What is the total (sample sum) of the sampling distribution of the sample sum of ages of these pennies?
A survey found that women's heights are normally distributed with mean 62.3 inches and standard deviation 2.2 inches. Most of the live characters employed at an amusement park have height requirements of at least 54 inches Find the percentage of women meeting the height requirement?
What does it mean when you have standard deviations of 27 35 and 32 and its effect on the validitity of the data you are accessing to interpret for statistical anaylsis?
Paint used to paint lines on roads must reflect enough light to be clearly visible at night. Researchers have 2 new types of paints they want to test paint type A and paint type B. For each paint type, they tested if there was statistical evidence the average reflectometer reading is greater than 35. To test each type of paint, they used 15 paint samples. Further, suppose the standard deviation is the same for both types of paints. The sample mean for paint type A was 39 and the sample mean for paint type B was 41.5. For both statistical tests, the significance level is set to .05.Which of the following is true? If they fail to reject the null hypothesis for paint type A we can conclude there is statistical evidence the average reflectometer for type A paint is 35. The p-value for the type B paint test is smaller. They rejected the null hypothesis for both paint types. Exactly two of the statements above are true. None are true.
