The owner of Prices Limited claims that 75% of all the items in the store cost less than $5. Suppose that you check a random sample of 146 items in the store and find that 105 cost less than $5. Does this indicate that the proportion of items in the store that cost less than $5 is different from 75%. Use a 5% level of significance (α = 0.05). State the null and alternate hypothesis.

Select one:
a. H0: p1 = p2; H1:p1 ≠ p2
b. H0: p = 0.75; H1:p ≠ 0.75
c. H0: p = 0.50; H1:p ≠ 0.50
d. H0: p = 0.75; H1:p < 0.75

hey i’m new i won’t be answering any questions now bye peeps see you next time

answer: just subtact the units and then add the non negative : happy to

step-by-step explanation:

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
