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.
The alpha level should always be set to 0.05.
The supplied statement;
How should you select the alpha() level when doing a significance test in practice,
⇒ Use a higher alpha when the consequences of wrongly rejecting the null hypothesis are more severe. Select alpha () = 0.05 in every situation since it is the best option. Use a smaller alpha when the consequences of wrongly rejecting the null hypothesis are more severe.
