-Random Variables
Cucumbers (you know, they are not just for salads.) grown on a farm, individually weigh between 2 ounces and 4 ounces in a uniform manner.
a.) Graph this distribution of weight of these cucumbers.
b.) What percent of these cucumbers weigh more than 2.8 ounces?
c.) What percent of these cucumbers weigh between 2.5 and 304 ounces?
d.) Find 83rd percentile.
e.) Find the mean.

Cucumbers grown on a certain farm have weights with a standard deviation of 2 ounces. Assuming the weights vary normally, what is the mean weight if 70% of the cucumbers weigh less than 14 ounces? Question 8 options: 14.45 13.25 15.05 12.95
R] Question 3 [Sans Say that you observe a two random variables, x1 and x2, from the continuous uniform distribution of [0,0].The continuous uniform distribution has density 0 otherwise. We would like to find an estimator for θ based on the data x1 and x2 What is the mcan squared error of the estimator i+ 2 (b). Let i - max(1, a2). The density of the estimator is 0 otherwise. hat is the mean squared error of the estimator r?...
R studio #Exercise : Calculate the following probabilities : #1. Probability that a normal random variable with mean 22 and variance 25 #(i)lies between 16.2 and 27.5 #(ii) is greater than 29 #(iii) is less than 17 #(iv)is less than 15 or greater than 25 #2.Probability that in 60 tosses of a fair coin the head comes up #(i) 20,25 or 30 times #(ii) less than 20 times #(iii) between 20 and 30 times #3.A random variable X has Poisson...
1. The service manager for Air Canada is uncertain about the time needed for the ground crew to turn an airplane around from the time it lands until it is ready to take off. He has been given information from the operations supervisor indicating that the times seem to range between 20 and 45 minutes. Without any further information, the service manager will apply a uniform distribution to the turnaround. (a) Define the density distribution/function. (b) What is the probability...
A manufacturer produces 25-pound lifting weights. The lowest actual weight is 24 pounds, and the highest is 26 pounds. Each weight is equally likely so the distribution of weights is uniform. A sample of 100 weights is taken. a. What is the distribution for the weights of one 25-pound lifting weight? What is the mean and standard deviation? b. What is the distribution for the mean weight of 100 25-pound lifting weights? c. Find the probability that the mean actual...

Let X be normally distributed with mean 100 cm and standard deviation 5 cm.
(a) On the diagram below, shade the region representing P(X > 105).
(2)
(b) Given that P(X < d) = P(X > 105), find the value of d.

I was wondering if you could help me with my statistics final
project. I just don't know how to start a hypothesis! At least
please help me form a topic and hypothesis and just briefly guide
me how to do. Thank you every much!!
