Answer:

first, it's not possible to leave answer in whole number. it's going to be in mixed fraction

ans is 4 11/16

Step-by-step explanation:

let the total amount be B and week be W

Total amount(b) is $145
Total week(w) is unknown

from equation b=70+(10+6)w

$145=70+16w

collect the like terms

$145-$70=16w

$75=16w

divide both by 16

75/16=16w/16

so, w= 75/16

4 11/16 or 4.7 rounding up to 1d.p

An agency that hires out clerical workers claims its workers can type, on average, at least 60 words per minute (wpmwpm). To tes

lapo4ka [179]

Answer:

The right answer is:

If the mean typing speed of workers from the agency is 60 wpmwpm, the probability of selecting a sample of 50 workers with mean 58.8 wpmwpm or less is 0.267.

Step-by-step explanation:

The P-value gives us the probability of getting the sample we are evaluating (in this case a sample with size n=50 and mean=58.8 wpm), if the null hypothesis is true (in this case, μ=60 wpm).

If the P-value is low enough, that is under the significance level, then we can infer that the mean that the null hypothesis states is not the actual mean, and we have evidence to reject the null hypothesis.
