Ascending Order:
When we talk about the numbers to be arranged in ascending order, it means the numbers need to be arranged from smallest to largest.
For example, if we have to arrange the numbers from 1 to 5 in ascending order.
It means, the ascending order will be: 1, 2, 3, 4, 5
Now, let us arrange the given numbers in ascending order.
a) 2234 to 2238 2234 2235 2236 2237 2238
b) 4099 to 4103 4099 4100 4101 4102 4103
c) 3298 to 3302 3298 3299 3300 3301 3302
d) 7269 to 7273 7269 7270 7271 7272 7273
e) 6354 to 6358 6354 6355 6356 6357 6358
f) 8379 to 8383 8379 8380 8381 8382 8383
g) 7365 to 7369 7365 7366 7367 7368 7369
Answer:
35 times 22 equals 770..........
Answer: 60 weeks.
Step-by-step explanation: 150 divided by 2.50 = 60
Answer:
The 90 % confidence limits are (-2.09, 8.09).
Since the calculated values do not lie in the critical region we accept our null hypothesis.
Step-by-step explanation:
The null and alternative hypothesis are given by
H0: σ₁²= σ₂² against Ha: σ₁² ≠ σ₂²
Confidence interval for the population mean difference is given by
(x`1- x`2) ± t √S²(1/n1 + 1/n2)
Where S ²= (n1-1)S₁² + S²₂(n2-1)/n1+n2-2
Critical value of t with n1+n2-2= 50+ 35-2= 83 will be -1.633
Now calculating
S ²=34* (12.8)²+ (14.6)²*49/83= 192.96
Now putting the values in the t- test
(75.1 -72.1) ± 1.633 √ 192.96(1/35 +1/50)
=3 ± 5.09
=-2.09, 8.09 is the 90 % confidence interval for the difference
The 90 % confidence limits are (-2.09, 8.09).
Since the calculated values do not lie in the critical region we accept our null hypothesis.
