Aresearcher tests how well participants know their spouse while under hypnosis, and again without hypnosis. it was hypothesized that participant responses would be more accurate (greater number of correct responses) when under hypnosis. the mean number of correct responses was m = 5.30 under hypnosis and m = 3.40 without hypnosis in a sample of 30 participants. if the estimated standard error for difference scores was 2.52, then what is the decision at a .05 level of significance (two-tailed test)?

a.
retain the null hypothesis; responses were not more accurate under hypnosis.

b.
retain the null hypothesis; responses were more accurate under hypnosis.

c.
reject the null hypothesis; responses were not more accurate under hypnosis.

d.
reject the null hypothesis; responses were more accurate under hypnosis

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.

what are you trying to solve here

step-by-step explanation:

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.
