How many numbers less than 904 are divisible by 3?

Mathematics

user100 [1]2 years ago
3 0

\Rightarrow T(n) = a + (n - 1)d

\Rightarrow 903 = 3 + (n - 1)3

\Rightarrow  903 = 3 + 3n - 3

\Rightarrow 3n = 903

\Rightarrow  n = 301

A: 301

Hitman42 [59]

Answer:

H0 rejected as μ>4

and a fish is unsafe to eat from the lake.

Step-by-step explanation:

1)Let the null hypothesis be  H0 : mu ≤4 against the alternate Ha: mu > 4 ppb

H0: μ ≤4   against the claim Ha:  μ>4

2) X`= ∑x/ n= 2.9 +7.6+ 4.8+ 5.2+ 5.1+ 4.7+ 6.9+ 4.9+ 3.7+ 3.8/10

= 49.6/10= 4.96

The standard deviation can be calculated  sigma= 1.344767 ( using statistic calculator)

3) The significance level is taken to be  ∝=0.05

The value of z at 0.05 for 1 sided test is z >± 1.645

i.e the critical region is less than - 1.645 and greater than +1.645

4) Taking the distribution to be approximately normal

Z= x`- u / s/ √n

Z= 4.96-4/ 1.345/10

Z= 4.96-4/ 1.345/3.1622

Z= 0.96/0.4253

Z= 2.257

5) Since the calculated value of z = 2.257 falls in the critical region we reject our null hypothesis and conclude that true mean value of the PCB concentration is greater than 4 (ppb) and that a fish is unsafe to eat from the lake.

15/16 = 0.9375
90% = 0.9
0.925 = 0.925
7/8 = 0.875
.92 = .92

0.875, 0.9, 0.92, 0.925, 0.9375

least to greatest = 7/8, 90%, .92, 0.925, 15/16
