Answer:
lenght: 192
Width 128
Height: 64
Step-by-step explanation
if every other thing is times height then height is x so you would do x+2x+3x = 384 and solve from there to get 384/6x= 64
and since width is 2 times that then 64 times 2 is 128 and times 3 is the lenght
The answer should be impossible, as it never said there were blue cards in that bag.
Concert 2/5 into a percent 5*20 = 100 (denominator) so 2* 20 =40
40/100 is 40%
I'm guessing you accidentally put the dor in front of 52 so it would be 40 at least and 52.57 at greatest
Answer:
Step-by-step explanation:
a) The null hypothesis is the hypothesis that is assumed to be true. It is an expression that is the opposite of what the researcher predicts.
The alternative hypothesis is what the researcher expects or predicts. It is the statement that is believed to be true if the null hypothesis is rejected.
From the given situation,
Carpetland salespersons average $8000 per week in sales. This is the null hypothesis.
H0: µ = 8000
Steve hopes that the results of a trial selling period will enable him to conclude that the compensation plan increases the average sales per salesperson. This is the alternative hypothesis.
Ha: µ > 8000
b) A type I error occurs when a true null hypothesis is rejected.
In this situation, a Type I error would occur if it was concluded that the new compensation plan provides a population mean weekly sales greater than 8000 (correct) when in fact it does not.
c) a Type II error would occur if it was concluded that the new compensation plan does not provide a population mean weekly sales greater than 8000 when in fact, it does.
