Suppose that a plumb of 1kg is repeatedly weighed to find the characteristics of a balance. The measured weights are known to follow a normal distribution with a mean of 1kg and a standard deviation of 50g. Now, we want to examine the characteristics of the data generated by the repeated measurements. Answer the following question using the 68-95-99.7 rule. Round from the 4th to the 3rd decimal place. Find the probability that the measured weight is between 0.95kg and 1.1kg.

I need to find the equivalence weight of a substance with a COOH group. I weighed out 0.150 grams of the substance and dissolved it in 30 mL ethanol. I titrated with 0.0999 M NaOH and used phenolptalein as an indicator. The color completely shifted form clear to a purple-reddish at 9.8 mL 0.0999 M NaOH added. I know that the substance only has one COOH group. The question is how i find the equivalence weight?

Suppose a game piece is initially at the starting point of the board. We repeatedly flip a fair coin and the piece is moved one step left or right on the board depending on whether the coin shows heads or tails. Approximate the probability that after 400 flips the piece is no more than 10 steps away from the starting position. Assume the board is infiniteso you don’t need to worry about hitting the edge. The answer of Probability equal...

A fair coin is flipped repeatedly. (a) (6pts) Suppose we hope that with probability at least 0.9 the frequency of heads showing up is between 0.4 and 0.6. Use Chebyshev’s inequality to estimate at least how many times the coin should be flipped. (b) (6pts) Suppose we hope that with probability at least 0.95 the frequency of heads showing up is between 0.4 and 0.6. Use the central limit theorem to estimate at least how many times the coin should...

A fair 6-sided die is rolled repeatedly. (a) Find the expected number of rolls needed to get a 1 followed right away by a 2. Hint: Start by conditioning on whether or not the first roll is a 1. (b) Find the expected number of rolls needed to get two consecutive 1’s. (c) Let an be the expected number of rolls needed to get the same value n times in a row (i.e., to obtain a streak of n consecutive...

Suppose that I flip a coin repeatedly. After a certain number of flips, I tell you that less than 80% of my flips have been “heads”. I flip a few more times, and then tell you that now more than 80% of my (total) flips have been “heads”. Prove that there must have been a point where exactly 80% of my flips had been “heads”. (If we replace 80% with 40%, the statement is not true: if I flip “tails”...
