Suppose that weight of men in a population has a normal distribution with mean 60 Kg and standard deviation 5 Kg. What percent of this population has weight between 58 Kg and 62 Kg? Show the probability on a graph. Calculate the 90th percentile of weight in this population, show it on graph, and interpret it. Use Minitab and round the answers to 2 decimal places.

Edit question fast please. The lengths of Atlantic Croaker Fish are normally distributed with mean of 10 inches and a standard deviation of 2 inches. An Atlantic croaker fish is randomly selected. Find the 75th percentile for the length of Atlantic croakers. Write the probability statement followed by the function used on the TI and followed by the probability value. The middle 60% of the length of Atlantic croakers fall between what values. Write the two numbers rounded to 2 decimal places separated by a comma.

Please draw a probability curve with your answer

The life of light bulbs is distributed normally. The variance of the lifetime is 225 and the mean lifetime of a bulb is 540 hours. Find the probability of a bulb lasting for between 532 and 571 hours. Round your answer to four decimal places.

Find the probability that the mean for 20 randomly selected distances is greater than 195.70 cm.

Assume that adults have IQ scores that are normally distributed with a mean of u = 100 and a standard deviation o = 15. Find the probability that a randomly selected adult has an IQ between 84 and 116. Click to view page 1 of the table. Click to view page 2 of the table. The probability that a randomly selected adult has an IQ between 84 and 116 is (Type an integer or decimal rounded to four decimal places as needed.)

According to the latest internet usage survey of college students, the amount of time spent on social media per day is normally distributed with a mean equal to 210 minutes  and a standard deviation of 45 minutes.  Based on this survey, find the probability that the amount of time spent on social media by college students is between 150 and 300 minutes per day.  Round answer to 4 decimal places.

The life of light bulbs is distributed normally. The variance of the lifetime is 900 and the mean lifetime of a bulb is 550 hours. Find the probability of a bulb lasting for at least 583 hours. Round your answer to four decimal places

Assume that adults have IQ scores that are normally distributed with a mean of u= 100 and a standard deviation g= 15. Find the probability that a randomly selected adult has an IQ less than 118. Click to view page 1 of the table. Click to view page 2 of the table. The probability that a randomly selected adult has an IQ less than 118 is (Type an integer or decimal rounded to four decimal places as needed.)

Assume that the samples are independent and that they hve been randomly selected. A marketing survey involes product recognition in New Yourk and California. Of 682 NEw Yorkers surveryed, 218 knew the product while 192 out of 518 californians knew the product. CAlculate the point estimates for both populations, the pooled sample, and the complement of the pooled sample. At the 0.05 significance level, test the claim that the recpgnition rates are the same in both states. Include your null and alternative hypothesis, the critical vaules, test statistic, P-value, decision about the null hypothesis, and an overall conclusion about the claim in your answer. Draw the z distribution. Construct a 95% confiecne interval estimate of the difference between the two population proportions. Explain how CI supports your decision about the null hypothesis.
