A sample of 56 research cotton samples resulted in a sample average percentage elongation of 8.63 and a sample standard deviatio
ss7ja [257]

To solve for the confidence interval for the true average percentage elongation, we use the z statistic. The formula for confidence interval is given as:

Confidence interval = x ± z σ / sqrt (n)

where,

x = the sample mean = 8.63

σ = sample standard deviation = 0.79

n = number of samples = 56

 

From the standard distribution tables, the value of z at 95% confidence interval is:

z = 1.96

 

Therefore substituting the known values into the equation:

Confidence interval = 8.63 ± (1.96) (0.79) / sqrt (56)

Confidence interval = 8.63 ± 0.207

Confidence interval = 8.42, 8.84

Consider the following cumulative probability distribution.
Marat540 [252]

The solution  P(x \leq 4),p{x= 3), p(2 \leq * \leq 4)  is mathematically given as

  • P(2 \leq X \leq 4)=0.84
  • P(X=3)= 0.17
  • P(2 < =X\leq 4)=0.53

<h3>What is the solution P(x \leq 4),p{x= 3), p(2 \leq * \leq 4)?</h3>

Generally, the equation for the Probability of P(X=3) is mathematically given as

b)

P(X=3) = P(X \leq 3)-P(X\leq 2)

Therefore

P(X=3)= 0.65-0.48

P(X=3)= 0.17

c)

P(2\leq X\leq 4) = P(X\leq 4)-P(X\leq 1)\\\\\\P(2\leq X\leq 4) = 0.84-0.31'

P(2 < =X\leq 4)=0.53

a)

P(2\leq X\leq 4)=0.84

At a fair, each person can spin two wheels of chance. The first wheel has the letters F, A, I, and R. The second wheel has the n
pickupchik [31]

Answer:

12 possible outcomes.

Sample space:

\begin{array}{cccc}(F,1)&(A,1)&(I,1)&(R,1)\\(F,2)&(A,2)&(I,2)&(R,2)\\(F,3&(A,3)&(I,3)&(R,13)\end{array}

Step-by-step explanation:

The collection of all possible outcomes of a probability experiment forms a set that is known as the sample space.

1. There are four possible outcomes for the first wheel: F, A, I and R

2. There are three possible outcomes for the second wheel: 1, 2 and 3

So, the sample space is

\begin{array}{cccc}(F,1)&(A,1)&(I,1)&(R,1)\\(F,2)&(A,2)&(I,2)&(R,2)\\(F,3&(A,3)&(I,3)&(R,13)\end{array}
