1)Assume that the data has a normal distribution and the number of observations is greater than fifty. Find the critical z value used to test a null hypothesis. Round to two decimal places. α = 0.07; alternate hypothesis H 1 is μ ≠ 3.24 LaTeX: \pm ± __________

2)Use the given information to find the P-value. The test statistic in a right-tailed test is z = 0.21. Round to two decimals.

3)Find the P-value for the indicated hypothesis test. A medical school claims that more than 14% of its students plan to go into general practice. It is found that among a random sample of 99 of the school's students, 25% of them plan to go into general practice. Find the P-value for a test of the school's claim. Round to 4 decimals.

5)Find the P-value for the indicated hypothesis test. An airline claims that the no-show rate for passengers booked on its flights is less than 5%. Of 380 randomly selected reservations, 18 were no-shows. Find the P-value for a test of the airline's claim. Round to 2 decimals.

The proportion of observations from a standard Normal distribution that take values greater than 1.631.63 is about (±±0.001)

For a Normal distribution with μ=10.6 and σ=2.6, what proportion of observations have values greater than...

For a Normal distribution with μ=10.6 and σ=2.6, what proportion of observations have values greater than 5? Is there a way I can calculate this on my graphing calculator? I know the answer to the problem but I can't seem to solve this correctly, I think my formulas may be off or I am missing a step.

1. Assume that your data comes from a Normal distribution. Further assume that the distribution has pop-ulation mean μ equal to your sample mean ̄x and population standard deviationσequal to your samplestandard deviations. Draw the graph of the Normal distribution described, labeling the mean and the tickmarks at standard deviation units. 2. We were sampling from the distribution of rainfall in a particular month. Assuming this distribution is Normal, find the proportion of years in which rainfall in the selected...

Find the z-score such that 35% of all observations (from a standard Normal distribution) are greater than z

For a standard normal distribution, what is the probability that z is greater than 1.65

A prime number (or prime) is a natural number greater than 1 that has no posítive...

A prime number (or prime) is a natural number greater than 1 that has no posítive divisors other than 1 and itself. Write a Python program which takes a set of positive numbers from the input and returns the sum of the prime numbers in the given set. The sequence will be ended with a negative number.

9. For a standard normal distribution, what is the probability that Z is greater than -1.35? Round to four decimals and use leading zeros. 10. For a standard normal variable, what is the probability that Z is between -2.00 and -1.00? Round to four decimals and use leading zeros. 11. For a dataset that follows the standard normal distribution, what is the probability that Z is between 2.00 and 3.00? Round to four decimals and use leading zeros.

A prime number is an integer greater than 1 that is evenly divisible by only 1 and itself. For example, the number 5 is prime because it can only be evenly divided by 1 and 5. The number 6, however, is not prime because it can be divided by 1, 2, 3, and 6.Write a Boolean function named isPrime, which takes an integer as an argument and returns true if the argument is a prime number, and false otherwise.
