Identify the missing numbers below to show the result of multiplying the numbers.
saveliy_v [14]
(3.5x1016) = 3556
and 
(2.2x1010) = 2222

As per question;
(3556)x(2222) = 10 a*b
By dividing both sides by "10"
we get
(3556)x(222.2) = a*b
or 
(355.6)x(2222) = a*b
by comparing both sides of the equation, 
we get that a = 3556  and b = 222.2
or 
a = 355.6 and b = 2222

For sample sizes greater than 40, the results of hypothesis tests and confidence intervals using the t distribution are highly s
dem82 [27]
We' supposed to indicate which statement is true/false.

Note that, if a sample size is 40 or over, we can use the t distribution even with skewed data. So it's not highly sensitive to non-normality of the population from which samples are taken. So statement A is false. 

It's true that the t-distribution assumes that the population from which samples are drawn is normally distributed. So B is true.

For skewed data or with extreme outliers, we can't use the t distribution. We only use t distribution as long as we believe that the population from which samples are drawn is closed to a bell-shape. So C is true.

 Lastly, statement D is against statement C. So D is false.
