Answer:
(a) Anova table is attached below.
(b) The population means of milk yield are different among the three diet types
Step-by-step explanation:
In this case we need to perform a One-way ANOVA to determine whether the effect of three diet types on the milk yield of cows are significantly different or not.
The hypothesis can be defined as follows:
<em>H</em>₀: The effect of three diet types on the milk yield of cows are same.
<em>Hₐ</em>: The effect of three diet types on the milk yield of cows are significantly different.
(a)
The formulas are as follows:
The F critical value is computed using the Excel formula:
F critical value=F.INV.RT(0.05,2,24)
The ANOVA table is attached below.
(b)
The rejection region is defined as follows:
F > F (2, 24) = 3.403
The computed F statistic value is:
F = 34.069
F = 34.269 > F (2, 24) = 3.403
The null hypothesis will be rejected.
Thus, concluding that the population means of milk yield are different among the three diet types
Answer:
The number of Bactria after 5.8 hours is 12242.
Step-by-step explanation:
The number of bacteria in a refrigerated food product is given by
where, T is the temperature of the food.
When the food is removed from the refrigerator, then the temperature is given by
We need to find the composite function N(T(t)).
where N(T(t)) is the number of bacteria after t hours.
Substitute t=5.8 in the above function.
Therefore, the number of Bactria after 5.8 hours is 12242.
