Write the null and alternative hypotheses you would use to test each of the situations in parts (a) through (c). (a) A governor is concerned about his "negatives," that is, the percentage of state residents who express disapproval of his job performance. His political committee pays for a series of TV ads, hoping that they can keep the negatives below 70 %. They will use follow up polling to assess the ads' effectiveness. Upper H 0 : The governor's "negatives" are ▼ decreasing. equal to 70%. less than 70%. greater than 70%. the same. increasing. not 70%. Upper H Subscript Upper A Baseline : The governor's "negatives" are ▼ equal to 70%. less than 70%. decreasing. the same. increasing. not 70%. greater than 70%.

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v
