The owner of an ice cream shop wants to determine whether there is a relationship between ice cream sales and temperature. the owner collects data on temperature and sales for a random sample of 30 days and runs a regression to determine if there is a relationship between temperature (in degrees) and ice cream sales. the p-value for the two-sided hypothesis test is 0.04. how would you interpret the p-value?
1)if there is no relationship between temperature and sales, the chance of selecting a sample this extreme would be 4%.
2)if there is a relationship between temperature and sales, the chance of seeing a regression coefficient this large would be 4%.
3)there is a 4% chance that there is a relationship between temperature and revenue.
4)there is a 4% chance that there is no relationship between temperature and revenue.

here we have to get the change of moles on decrease the volume of the reaction in gas phase.

the   per the given options it will decrease by (d) 11-50%

we know, on decreasing the volume of the gas phase reaction the reaction moves to the product side.

the reaction:                     so₂cl₂ (g) = so₂ (g) + cl₂ (g)         total

the moles at equilibrium:   1 - α                 α               α           = 1+α

concentrations:                   1 - α               α               α           = 1 + α

(concentration = moles/volume, as volume is 1 l)

(where α is the degree of dissociation)

now the dissociation constant in terms of concentration is :

=  

or,

or,   = (at v = 1l)

the reaction:                     so₂cl₂ (g) = so₂ (g) + cl₂ (g)         total

the moles at equilibrium:   1 - α                 α               α           = 1+α

concentrations:               (1 - α)/0.5           α/0.5         α/0.5       = (1 + α)/0.5

thus, the dissociation constant in terms of concentration is :

or,  

=  

so, the change of 1 : 1/0.5

or, 1: 2

thus it will decrease by 50%.

or, as per the given options it will decrease by 11-50%

u i forgot the answer?
