Answer: 27.688
Step-by-step explanation:
The critical chi-square value depends on significance level (
) and degrees of freedom (df) .
Given significance level: () = 1% = 0.01
Degrees of freedom (df)= 13
From the chi-square table, the critical chi-square value for df = 13 and
is
Hence, the required critical value = 27.688
Answer:
Thus, the equation hat correctly represents the number of ounces of beef stock, , that the chef initially prepares.
⇒
The total number of ounces of beef stock = 126
Step-by-step explanation:
Given:
Total ounces of beef stock =
The chef divided the beef stock evenly into 3 smaller pans.
The chef then uses 8 ounces from one of the smaller pans.
Ounces of beef stock left in the smaller pan = 34
Solution:
Total ounces of beef stock =
Ounces of beef stock in each smaller pan =
Ounces of beef stock used by the chef from the smaller pan = 8.
The ounces of beef stock left in the smaller pan will be given as:
⇒
Ounces of beef stock remaining in smaller pan = 34
Thus, the equation hat correctly represents the number of ounces of beef stock, , that the chef initially prepares.
⇒
Solving for .
Adding 8 both sides.
⇒
⇒
Multiplying both sides by 3.
⇒
∴
Thus, total number of ounces of beef stock = 126
