Answer:
Step-by-step explanation:
Sample data
204.999 206.149 202.102 207.048 203.496 206.343 203.496 206.676 205.831
N=9
Sum, Σx: 1846.14
Mean, μ: 205.12666666667
Variance, s^2: 2.6217475555555
Std dev = s = 1.619
The sample mean follows a t distribtion with df =8
Mean difference = 205.13-204.8 = 0.50
Std error = std dev/sqrt n = 0.540
Test statistic = Mean diff/se = 0.9259
p value = 0.1907 (one tailed at 95%)
Since p >0.05 we accept null hypothesis.
We cannot conclude that the mean shade of Mezza Perla tile (µ) is greater than 204.8
Answer:
k = 11 let me know if you don't understand how I got this.
Step-by-step explanation:
I'm gonna write it out
U V total
S 26 42 68
T
21 k 32
Total 47 53 100
So, you want to look at the column and row labeled total, this is the key. for the row total, it sums up everything in the column above it. so for the u column, the total value is 47 while the two values above it are 26 and 21. These two values sum to 47. This is the same for all other columns, and you can use the same reasoning with the total column as well summing rows.
This gives you two ways to solve for k. either 21 + k = 32 or 42 + k = 53. Either way gets you the answer k = 11
Answer: 
Step-by-step explanation:
Given : Significance level : 
Sample size : n=85
Critical value : 
Sample mean : 
Standard deviation : 
The confidence interval for population mean is given by :-
Thus, the 95% confidence interval for the true mean cholesterol content, μ, of all such eggs =
Hence, we conclude that the true population mean of amount of cholesterol lies between 182.356 and 197.644.
The answer to number 1 is number cards 31 and 37. The answer to number 2 is number cards 61 and 54. On number 3, you could say, Mickeyy1 has these number cards. You then make 1 card over 30 and one card less than 22. Your final cards would be, 19, 23, 25, 27, and 32. You would get rid of the cards over 30 or less than 22. Therefore, you would keep number cards 23, 25, and 27. You would get rid of 19 and 32.
