A researcher wants to determine if birthweights of children born to U.S. mothers is affected in any way when large megadoses of caffeine are consumed routinely by the mother during pregnancy. It is known that the birthweights are normally distributed with mean 7.5 pounds and standard deviation 1 pound. When drawing a sample of size 40 from such a population, and computing the mean birthweight in the sample, use the Central Limit Theorem to find the 2.5-th percentile of the distribution of sample means.

What is confidence interval?

A confidence interval (CI) for an unknown parameter in frequentist statistics is a range of estimations. The most popular confidence level is 95%, but other levels, such 90% or 99%, are occasionally used for computing confidence intervals. The fraction of related CIs over the long run that actually contain the parameter's true value is what is meant by the confidence level. The degree of confidence, sample size, and sample variability are all factors that might affect the width of the CI. A larger sample would result in a narrower confidence interval if all other factors remained constant. A wider confidence interval would also be required by a higher confidence level and would be produced by a sample with (1.645 / 0.03)2 * 0.5 * 0.5

=752

Sample size = 752

= 1 - 0.42 = 0.58

margin of error = E =3 % = 0.03

At 90% confidence level z

Hence, The sample size just be 752.

Points F (0,0), G (9,0), and H (9,12) are the vertices of a triangle.What is the distance from point F to point H?

A. 9
B. 12
C. 15
D. 21

Answers

The distance from point F to point H is 15 units. Option C is correct.

In order to get the distance from point F to point H, we will use the distance formula as shown:

$D =√((x_2-x_1)^2+(y_2-y_1)^2)$

Given the coordinate points F(0,0) and H(9, 12)

$FH=√((12-0)^2+(9-0)^2)\nFH =√(12^2+9^2)\nFH=√(144+81)\nFH=√(225)\nFH = 15units$

Hence the distance from point F to point H is 15 units. Option C is correct.

Whats the question ELAISSAROYER22

The number of minutes that Samantha waits to catch the bus is uniformly distributed between 0 and 15 minutes. What is the probability that Samantha has to wait less than 4.5 minutes to catch the bus? a. 10%
b. 3%
c. 20%
d. 30%

Answers

Answer:

option d. 30%

Step-by-step explanation:

Data provided in the question:

$a=0$

$b=15$

Now,

The probability density function of the uniform distribution is given as:

$f(x)=(1)/(15-0)$

$f(x)=(1)/(15), 0<x<15$

Therefore,

The required probability will be

$P(X<4.5)=\int_(0)^(4.5) f(x) d x$

$P(X<4.5)=\int_(0)^(4.5) (1)/(15) d x$

$P(X<4.5)=\left((x)/(15)\right)_(0)^(4.5)$

$P(X<4.5)=\left((4.5)/(15)-(0)/(15)\right)$

$P(X<4.5)=0.3$

= 0.3 × 100%

= 30%

Hence,

The answer is option d. 30%

Final answer:

In a uniform distribution, all values have an equal chance of occurring. To find the probability of Samantha waiting less than 4.5 minutes, you divide 4.5 by the total time interval of 15 minutes. The answer is 30%.

Explanation:

The question is about the concept of uniform distribution in probability, which means that each value within the given range has an equal chance of being drawn. In this case, Samantha can wait anywhere between 0 and 15 minutes, so each minute has an equally likely chance of being the waiting time. To find the probability that Samantha has to wait less than 4.5 minutes, we simply divide this time interval by the total time interval. Hence, the calculation is 4.5 / 15 = 0.30 or 30%. So, the answer to the question of the probability that Samantha has to wait less than 4.5 minutes to catch the bus is 30%.
