2.30% equals 2.30 as a decimal, 1/5 equals 0.2 as a decimal. So it would be: 1/5, 0.23, 2.30

Ok so it is a standard deck of 52 cards. Theres 4 suites: Hearts, Spades, Clubs and Diamonds.
In each suite there is 13 cards: Ace, King, Queen, Jack, 10, 9, 8, 7, 6, 5, 4, 3, and 2. The probability of you choosing 5 hearts is most likely to be 5/52.
In this
problem, the given values are:
x = average =
30.4
s = standard
deviation = 7.1
n = number of
samples = 25
Degrees of
freedom = n -1 =24
Using the
t-distribution table for a normal curve at 90% CI, we get t-crit:
t-crit = 1.711
Now the Margin
of Error (E) is calculated as:
E = t-crit*(s/
)
By substituting the known values into the equation:
E = 1.711 * (7.1/
)
E = +- 4.30
Therefore, the margin of error is 4.36. Hence, the commute time
is between 26.1 minutes and 34.7 minutes.
