35 Bananas, becuse if every 2 equals 5, divide 14 by two which equals 7, then muliply 7 by 5.
Answer:
Step-by-step explanation:
Given that:
The null hypothesis:
The alternative hypothesis:
Suppose the number of samples n from the population is 16
The observed value x of the test statistics for testing the hypothesis for this study is x = 14
However, if the null hypothesis is true, then the distribution of the test statistics follows a binomial distribution which is expressed as:
bin(n=16, p = 0.5) distribution
The p-value for this test statistics can be computed as:
p-value = P(X ≥ 14)
p-value = 1 - P (X ≤ 13)
p-value =
p-value =
p-value = 0.00209
Answer:
c.132
Step-by-step explanation:
so we are given the diameter which is 42m **the diameter is the straight line that passes through the middle of the circle**
but in order to find the circumference we need to find the radius **the radius is always half (1/2,0.5) of the diameter**
so we have to divide 42/2 which equals 21
now we need to set up the formula;
c=2πr/c=2xπxr **when unknown variables such as 'r' are next to another mathematical numeral such as the pi symbol you don't really have to but the multiplication symbol between them**
c=2π21
=131.946891451
and in your case, it seems we must round to the tenths place so the nine then "becomes a ten" and you're left with 132
good luck :)
i hope this helps
have a good one !!
Answer:
There is sufficient evidence to support the claim that the new balls have bounce heights with a mean different from 92.8292.82 inches, and it appears that the new baseballs are different
Step-by-step explanation:
Given that in previous tests, baseballs were dropped 24 feet onto a concrete surface, and they bounced an average of 92.82 inches
But new balls showed mean of 92.6 inches with s = 1.72 inches
Sample size = 23
Since sample size is less than 30 and population std deviation is not know we use t test
(Two tailed test at 5% significance level)
Mean difference =
Std error of sample mean = s/sqrt n =
Test statistic t = mean diff/std error = -3.402
df = 23-1 =22
p value = 0.002559
since p value <5% we reject H0
There is sufficient evidence to support the claim that the new balls have bounce heights with a mean different from 92.8292.82 inches, and it appears that the new baseballs are different
