can someone please use numbers on how to solve this equation. every example I see is them using the symbols. thank you so much.
The average THC content of marijuana sold on the street is 9.1%. Suppose the THC content is normally distributed with standard deviation of 2%. Let X be the THC content for a randomly selected bag of marijuana that is sold on the street. Round all answers to 4 decimal places where possible,
a. What is the distribution of X? X ~ N(,)
b. Find the probability that a randomly selected bag of marijuana sold on the street will have a THC content greater than 9.2.
c. Find the 75th percentile for this distribution. %

Question 1 1 pts The average THC content of marijuana sold on the street is 10%. Suppose the THC content is normally distributed with standard deviation of 2%. Let X be the THC content for a randomly selected bag of marijuana that is sold on the street. Round all answers to two decimal places and give THC content in units of percent. For example, for a THC content of 11%, write "11" not 0.11. AX-NO ) B. Find the probability...
Can someone please help me with my central limit theorem homework? Thank you much! 1. A population has parameters μ=36.3 and 57.1. You intend to draw a random sample of size n=139. a. What is the mean of the distribution of sample means? μ¯x= _________________ b. What is the standard deviation of the distribution of sample means? (Report answer accurate to 2 decimal places.) σx¯=_______________ 2. A population of values has a normal distribution with μ=201.8μ=201.8 and σ=90.9σ=90.9. You intend...
Please answer all parts, questions 1-5. Thank you! To represent normal variable (distribution) with mean() and standard deviation (0) we use shorthand notation X-N . a). For example, suppose the vitamin C content of a particular variety of orange is distributed normally with mean 720 IU and standard deviation 46 IU. If we designate the vitamin C content of a randomly selected orange, then our shorthand notation is X-N[720 IU, 46 IU). To represent probability between two values a and...
can someone help me answer these please! i am stuck and these are the only questions i do not get it would be a huge help please Question Help Assume that thermometer readings are normally distributed with a mean of oC and a standard deviation of 1.00°C. A thermometer is randomly selected and tested. For the case below, draw a sketch, and find the probability of the reading. (The given values are in Calsius degrees.) Between 0.75 and 1.75 Click...
if someone could give an explanation for D. the answer is 0.37%. I would just like to know how they got that answer in steps. Statistics Assignment 17 1) Find the upper and lower -Scores for the middle 50% of a normal distribution. What percentiles do these numbers represent? 22101 2.61 2) What is the range of z-scores that are outliers for the normal distribution? 2.63 X 3) The Wechsler IQ test is designed to assess human intelligence. I should...
EXAMPLE I: Consider the weights of 18 month old boys in the U.S. According to published growth charts, the average weight is approximately 11.8 kg with standard deviation of 1.28 kg. Calculate the percentage of 18 month old boys in the U.S. who weigh between 10.5 kg and 14.4 kg. Solution: So X- N(11.8, 1.28). We need P(10.5<X<14.4) Here: Lower boundary- 10.5 Second: Upper boundary 14.4 Third: u-11.8 Fourth: 6-1.28 Now normaledf(10.5, 14.4, 11.8, 1.28) 824 We want to convert...
IN EXCEL SO I CAN SEE THE FORMULAS USED. Open the Excel program Suppose we want to know the standard normal distribution up to the given value. That is P(Z <a). Lets use Excel instead of the standard normal distribution table In cell A1 type mean. In cell B1 type 0. That means that we are letting mean be zero. click on cell A2 and type SD. In cell B2 type 1. That means that we are letting standard deviation...
please help with all you can. answer 10 ill give a thumbs up! Question 1 A particular fruit's weights are normally distributed, with a mean of 263 grams and a standard deviation of 23 grams.
