Consider the following hypothesis test:
H0: n greater than or equal to 20
Ha: n less than 20
a sample of 45 provided a sample mean of 19.6. the population
standard deviation is 1.8
a. Compute the value of the test statistic (to 2
decimals). Enter negative value as negative number.
_______
b. what is the p-value? (3 decimals)
d. using a=0.05, what is the critical value for the test
statistic (to 3 decimals)? Enter negative value as negative
number.
________...
Prove the statement by using definitions and assumptions only:
if an integer greater than 4 is a perfect square then the
immediately preceding integer is not prime.
Design a Turing machine that, given a positive binary number n
greater than or equal to 2, subtracts 2 from this number. Test it,
step-by-step, on the example of n = 2.
Let n greater than or equal to 2 and let k1,...,kn be
positive integers. Recall that Ck1,..., Ckn denote the cyclic
groups of order k1,...,kn. Prove by induction that their direct
product Ck1×Ck2×....×Ckn is cyclic if and only if the ki's are
pairwise coprime which means gcd(ki,kj)=1 for every i not equals j
in {1,...n}.
For each of the following, fill in the blanks with "Less than",
"Greater than", or "Equal to"
*) A gas flows through a one-inlet, one-exit control volume
operating at steady state with no internal irreversibilities, Qcv =
0. Heat transfer at a rate Qcv takes place only at a location on
the boundary where the temperature is Tb. The specific entropy of
the gas at the exit is _____ than the specific entropy of the gas
at the inlet.
*)...
The
work input to an ideal pump will always be greater than or equal to
the work input of an actual pump with the same working fluid, Inlet
State, and outlet pressure. True or false?
