Weights of Elephants A sample of 7 adult elephants had an average weight of 11,647 pounds. The standard deviation for the sample

SCORPION-xisa [38]

Answer:

The 95 % confidence interval of the population mean for the weights of adult elephants

(11,629.375 , 11,664.625) up to three decimals

Nearest whole number

(11,629 , 11,665)

Step-by-step explanation:

Explanation:-

A sample of 7 adult elephants had an average weight of 11,647 pounds

size of the sample 'n' =7

The mean of the sample x⁻ = 11,647 pounds

The standard deviation of the sample 'S' = 24 pounds

Step(ii):-

The 95 % confidence interval of the population mean for the weights of adult elephants

$(x^{-} - t_{0.95} \frac{S}{\sqrt{n} } , x^{-} + t_{0.95} \frac{S}{\sqrt{n} } )$

The degrees of freedom γ =n-1 = 7-1=6

t₆ = 1.943

$(11,647 - 1.943 \frac{24}{\sqrt{7} } , 11,647 + 1.943 \frac{24}{\sqrt{7} } )$

(11,647-17.625 , 11,647+17.625)

(11,629.375 , 11,664.625)

Conclusion:-

The 95 % confidence interval of the population mean for the weights of adult elephants

(11,629 , 11,665)

Give a base class with at least one public member function, how many child classes can redefine that member function? a. 1 b. 0

solong [7]

Answer:

C. All of them

Step-by-step explanation:

The base class is the super/parent class of a child class; so a child class inherit from a base class.

When a child class inherit from a base class; it have access to redefine the member function that is declared public. 'public' is an access modifier which means it can be access from outside the class and modified.

Therefore, all the child class which inherit the base class can redefine the member function that are public.
