Suppose we wish to estimate the mean heart rate, using a 95%
confidence interval, for a par- ticular population. We observe 130
individuals to see a sample mean of 98.249 and a sample standard
deviation of 0.733. We then find the tc-value, corresponding to the
value on the t-distribution (d.f. = 130) so that the area to the
left of it is equal to 95%, which ends up being:
tc ≈ 1.656659.
Next we compute the error and obtain our...

Suppose we want to transmit the message 10011010 and protect it
from errors using the CRC polynomial x2+1.
(8 points) Encode the data bit sequence using the generator
polynomial and give the code word.
(8 points) Using this polynomial, can all single-bit errors be
detected? If not, give an example scenario of errors that goes
undetected.

Question 1
We wish to see if, on average, traffic is moving at the posted
speed limit of 65 miles per hour along a certain stretch of
Interstate 70. On each of four randomly selected days, a randomly
selected car is timed and the speed of the car is recorded. The
observed times were:
70 65 70 75
Assuming that speeds are normally distributed with mean
m, is there evidence that the mean speed is not equal to
the posted speed limit?

Suppose we are given a set ? containing 2? integers, and we wish
to partition it into two sets ?1 and ?2 so that |?1 | = |?2 | = ?
and so that the sum of the numbers in ?1 is as close as possible to
the sum of those in ?2. Let the neighborhood ? be determined by all
possible interchanges of two integers between ?1 and ?2. Is ?
exact?

Suppose we want to transmit the message 0010
1101 and detect transmission errors using the CRC divisor
polynomial
(x3+x2+1).
A.) [15 marks] Determine the bit string that should be
transmitted.
B.) [15 marks] If the leftmost 1-bit
of the transmitted string is inverted due to noise on the link,
what is the result of the receiver's CRC calculation?

Question 1 Consider the production function:F(L,K) = L^1/3 K^1/3
.
Suppose the wage rate (price per unit of labour), w, is 2 and
the capital rental rate (price per unit of capital), r, is 1.
(a) Does this production function exhibit increasing, decreasing
or constant returns to scale? Explain.

your answer to (c) to answer this question.) Find the total cost of
producing 32 units of...

Suppose that we wish to test a claim that a sequence of sample
data was produced in a random manner, and suppose that each data
value belongs to one of two categories. Let n1n1 be the number of
elements in the sequence that belong to the first category, n2n2 be
the number of elements in the sequence that belong to the second
category, and GG be the number of runs in such a sequence.
