Maru [420]

Answer:

0.077994

Step-by-step explanation:

Given that the owner of a local nightclub has recently surveyed a random sample of n = 250 customers of the club.

$H_0: Mean = 30\\H_a: Mean >30$

(Right tailed test)

Sample size = $n=250$

Sample mean = 30.45

Mean difference = $30.45-30=0.45\\$

Sample std dev s = 5

Sample std error = $\frac{5}{\sqrt{n} } =\frac{5}{\sqrt{250} } \\=0.3163$

Test statistic = Mean diff/std error = $=\frac{0.45}{0.3163} =1.423$

Since population std deviation is not know we use t test

p value = $0.077994$

At the start of the year, the balance in a married couple’s account is $ 1 , 750 . They decide to each deposit $ 35 into the acc

Dimas [21]

Answer:

f(n) = 1750 + 70n

Step-by-step explanation:

Since, each of them are depositing 35$ each month, they are adding 35x2 = 70$ each month.

So, in n months, they will be adding 70n $ to their account.

Initially, they had 1,750$ in their account. After n months, they should have 1750+70n $ in their account.

So, the function that represents this is, f(n) = 1750 +70n
