The personnel manager at a company wants to investigate job satisfaction among the female employees. one evening after a meeting she talks to all 30 female employees who attended the meeting. does this sampling plan result in a random sample? simple random sample? explain.

No, it is not random sample.

Step-by-step explanation:

Since chances of attending the meeting are only a particular type of female employee either they have the same designation or have the same job profile, So selecting these female employees is not random, As the selection of each female employee of a company does not have an equal chance of selection.

Further, Simple Random Sampling is the sampling when samples are chosen randomly, where each unit has an equal chance of being selected in a sample.

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)

6mm^3 or .6cm^3

factor trees are nice.
