Answer: -1.5
Step-by-step explanation:
When population standard deviation is known, then the formula to find the z-test statistic for population mean is given by :-
, where n= Sample size.
= Population mean
= Sample mean
= Population standard deviation.
As per given , we have (average infants contracted typhoid each month)
n= 4 (No. of months)
Then , the value of the appropriate test statistic will be :
Hence, the value of the test statistic = -1.5
Answer:
The function that best models the given data is;
B. h(t) = -6.73·t² + 14.19·t + 0.83
Step-by-step explanation:
The data in the given table is presented as follows
Where;
Time, t(s) is the independent variable
Height, h(m) is the dependent variable
Therefore, we have;
When t = 0, h = 1.0
From the given functions, we have the following table of the result of the function generated with Microsoft Excel
By comparison, the function that nest models the given data is the function 'B', given as follows;
h(t) = -6.73·t² + 14.19·t + 0.83.
