Wat is the scientific notation for 0.00000012 and 0.000005008
gtnhenbr [62]
Scientific notation is a way of writing numbers in a form of a decimal multiplied by an exponent of 10.
For these, the exponent will be negative, since they're teeny tiny decimals, and we'll have to move the decimal point back to the right.
0.00000012 will become 1.2* 10^{-7}
This is because the decimal point is moved seven places to the right of where it originally was.
0.000005008 will become 50.08* 10^{-7}
Again, this is because the decimal point is moved seven places to the right of where it originally was.
So, your scientific notations are 1.2* 10^{-7} and 50.08* 10^{-7}

A hotel wants to know if there's a relationship between gender and the way customers make room reservations. A manager takes a r
padilas [110]

Answer:

Step-by-step explanation:

Here,

H_o: The way of reservation is independent of gender.

H_a: The way of reservation is not independent of gender.

We use a chi square test because we can calculate the expected frequencies for this chart.

Doing an Expected Value Chart,          

         

33.7625   9.7125   30.525  

39.2375   11.2875   35.475

Using chi^2 = Sum[(O - E)^2/E],          

chi^2 =    4.482385929

With df = (a - 1)(b - 1), where a and b are the number of categories of each variable,

a =    3      

b =    2

df =    2

Thus, the critical value is

significance level =    0.05

chi^2(critical) =    5.991464547

Also, the p value is

P =    0.106331579

Thus, comparing chi^2 and chi^2(critical) [or, p and significance level], we   FAIL TO REJECT THE NULL HYPOTHESIS.

Thus, there is no significant evidence that the way of reservation is dependent of gender. [CONCLUSION]
