Conclusion. 6. From a random sample of 51 litters of rats, the mean litter size is 6.11, with an assumed population standard deviation is 2.27. Construct a 94% confidence interval for the mean litter size of rats (these values are based on data gathered by King in 1924). 7. Using the data from problem #6, what sample size would have been necessary for a ...

Sum of original 6 numbers = 20 × 6 = 120. Sum of remaining 5 numbers = 15 × 5 = 75. Number removed = sum of original 6 numbers – sum of remaining 5 numbers. Number removed = 120 – 75 = 45. Alternative Method: Let x be the removed number. The removed number is 45. Example: 10 students of a class had a mean score of 70.The z -score of 72 is (72 – 70) / 2 = 1. Thus we are looking for the area under the normal distribution for 1< z < 1.5. A quick check of the normal distribution table shows that this proportion is 0.933 – 0.841 = 0.092 = 9.2%.

Step 1: Assign events to A or X. You want to know what a woman’s probability of having cancer is, given a positive mammogram. For this problem, actually having cancer is A and a positive test result is X. Step 2: List out the parts of the equation (this makes it easier to work the actual equation): P (A)=0.01.The most common descriptive statistics are in the following table, along with their formulas and a short description of what each one measures. Statistically figuring sample size When designing a study, the sample size is an important consideration because the larger the sample size, the more data you have, and the more precise your …Solved Statistics Problems – Practice Problems to prepare for your exams.

tanner gramke Mar 18, 2017 · By using the z-score formula: z = ( x - μ) / σ we can convert any distribution to the standard normal distribution. Here the Greek letter μ the mean and σ is the standard deviation. The standard normal distribution is a special normal distribution. It has a mean of 0 and its standard deviation is equal to 1.
