Solving these useing R program using pnorm() for Statistics
Please show the code you used and the answer Thank you
The fracture toughness (in ???√?) of a particular steel alloy is known to be normally distributed with a mean of 28.3 and a standard deviation of 0.77. We select one sample of alloy at random and measure its fracture toughness.
▶ What is the probability that the fracture toughness will be between 27.8 and 30.7?
▶ What is the probability that the fracture toughness will be at least 29.5?
▶ Given that the fracture toughness is at least 29, what is the probability that the fracture toughness will be no more than 30.5?

1. Assume that ? is a random variable follows binomial
probability distribution with parameters 15 and
0.25.
a. Simulate 100 binomial pseudorandom numbers from the given
distribution (using set.seed(200)) and assign them to vector called
binran.
b. Calculate ?(? < 8) using cumulative probability
function.
c. Calculate ?(? = 8) using probability distribution
function.
d. Calculate the average of simulated data and compare it with
the corresponding...

mean 60 hours.
a. Simulate 500 pseudorandom numbers (using set.seed(10)) and
assign them to a vector called expran.
b. Calculate average of simulated data and compare it with
corresponding theoretical value.
c. Calculate probability that lifetime is less than 50 hours using
cumulative probability function.

Are Angry People More Likely to have Heart Disease’? People who
get angry easily tend to be more likely to have heart disease. That
is the conclusion of a study that followed a random sample of
12,986 people from three locations over about four years. All
subjects were free of heart disease at the beginning of the study.
The subjects took the Spielberger Trait Anger Scale, which measures

A bottling company uses a machine to fill bottles with a tasty
beverage. The bottles are advertised to contain 300 milliliters
(ml), but in reality the amount varies according to a normal
distribution with mean μ=298ml and standard deviation σ=3 ml. (For
this problem, we’ll assume σσ is known and carry out the
calculations accordingly)....

Please do this question in R and show the code too, please.
The alternating current (AC) breakdown voltage of an insulating
liquid indicates its dielectric strength. The article “Testing
Practices for the AC Breakdown Voltage Testing of Insulation
Liquids” (IEEE Electrical Insulation Magazine, 1995: 21–26) gave
the accompanying sample observations on breakdown voltage (kV) of a
particular circuit under certain conditions.
