In sports​ betting, sports books establish winning margins for a team that is favored to win a game. An individual can place a wager on the game and will win if the team bet upon wins after accounting for this spread. For​ example, if Team A is favored by 5​ points, and wins the game by 7​ points, then a bet on Team A is a winning bet.​ However, if Team A wins the game by only 3​ points, then a bet on Team A is a losing bet. Suppose that in​ games, the margin of victory for the favored team relative to the spread is approximately normally distributed with a mean of
−1.0
point and a standard deviation of
11.1
points. Complete parts​ (a) through​ (c) below.
​(a) What is the probability that the favored team wins by
7
or more points relative to the​ spread?
 
The probability is
nothing.
​(Round to four decimal places as​ needed.)
​(b) What is the probability that the favored team loses by
3
or more points relative to the​ spread?
 
The probability is
nothing.
​(Round to four decimal places as​ needed.)
​(c) In games where a team is favored by more than 12​ points, what is the probability that the favored team​ "beats the​ spread"? Does this imply that the possible point shaving spreads are accurate for games in which a team is favored by more than 12​ points?
 
The probability is
nothing.
​(Round to four decimal places as​ needed.)
Does this imply that the possible point shaving spreads are accurate for games in which a team is favored by more than 12​ points?
 
 
A.
The fact that the favored team is less likely to lose than to win relative to the spread means that the spreads are not accurate. There is possible point shaving.
 
B.
The fact that the favored team is just as likely to lose as they are to win relative to the spread means that the spreads are accurate. There is no evidence of point shaving.
 
C.
The fact that the favored team is just as likely to lose as they are to win relative to the spread means that the spreads are not accurate. There is possible point shaving.
 
D.
The fact that the favored team is more likely to lose than to win relative to the spread means that the spreads are not accurate. There is possible point shaving
