A car owner conducts an experiment by filling up their car with 10 gallons of gas and drives until it runs out of gas. The number of miles driven from the 10 times of doing this experiment is shown below:

275 240 303 243 259 187 311 276 251 263

Find the following: Show ALL necessary work

a) Median

b) Lower and Upper Quartiles

c) IQR

d) State the mild outliers, if any. If there are no outliers, then state "no outliers".

John performs a similar colligative property experiment as Exp 22. He prepared a solution by mixing 11.2 g of naphthalene, C10H8(s), in 350.0 g of cyclohexane.If John measured the freezing point of this solution to be 1.28 celsius, what is the relative error in John's experiment?

Molar mass Freezing Point Freezing Point Depression
Cyclohexane 84.16 g/mol 6.55 celsius 20.20 celsius/m
Napthalene 128.17 g/mol 80.26 celsius 6.80 celsius/m

A boxcar contains six complex electronic systems. Two of the six areto be randomly selected for thorough testing and then classified as defective or not defective.

(a) Describe the sample spaceSof this experiment and give its cardinality

(b) Explain why this is an equally likely experiment

(c) If two of the six systems are actually defective, find:

(i) the probability that at least one of the two systems tested will be defective

(ii) the probability that both are defective.

Note:Please leave all your answers to this question in combination formula.

design an experiment to determine the concentration of HbA1c in the blood sample by following these six steps

Step 1, pick one differentiating characteristic

Step2 how will u probe that differentiating characteristic

Step3 tell the anticipated response to the probe

step4 measure the response to the probe

step 5 how will u interpret the response to the probe to obtain the desired information

step6 tell the likely interference with the method you have chosen.

you have to design experiment to tell the concentration of HbA1c

Consider the following experiment: Simultaneously toss a fair coin and, independently, roll a fair die.

  1. Write out the 12 outcomes that comprise the sample space for this experiment.
  1. Let X be a random variable that takes the value of 1 if the coin shows “heads” and the value of 0 if the coin shows “tails”. Let Y be a random variable that takes the value of the “up” face of the tossed die. And let Z = X + Y. Construct the probability mass function for Z.
  1. Find the mean for Z.
  1. Find the variance for Z.

Answer true or false and explain for the following six statements:

The null hypothesis is that all four means are equal.

The calculated value of F is 4.500.

The critical value for F for 5% significance is 6.06.

The null hypothesis cannot be rejected at 5% significance.

The null hypothesis cannot be rejected at 1% significance.

There are 10 observations in the experiment.
