Answer:
d. 2/9
Step-by-step explanation:
7/8 - 0.85
3/5 - 0.6
5/2 - 2.5
2/9 - 0.222... the two is a recurring number
Answer:
see below
Step-by-step explanation:
The problem statement seems to presume you have seen an exponential function like this written as ...
f(t) = a0·(1 +r)^t
where a0 is the value corresponding to f(0) and "r" is the fractional rate at which the value increases for each increment of t.
Here, 1+r corresponds to 1.04 in the given function, so r = 0.04 = 4%. When the value is <em>greater than 0</em>, it means there is an <em>increase</em> by that fraction each time t increases by 1.
Here, t is not defined, either, but it would usually be used to represent years in a situation like this. (In other situations, it might represent months, hours, or millenia.)
Hence, the appropriate choice is the one that describes a 4% annual increase.
Answer:
C. H0: PL - PR = 0
Ha: PL - PR > 0
The null hypothesis for this case is that left-handed pitchers in a baseball league are not more likely to strike out batters than right-handed pitchers are. That is the proportion of at-bats resulting in a strikeout is significantly equal for both left-handed and right-handed pitchers.
H0: PL - PR = 0
The alternative hypothesis is that the proportion of at-bats resulting in a strikeout is significantly higher for left-handed pitchers
Ha: PL - PR > 0
PL - proportion of at-bats resulting in a strikeout for left-handed pitchers
PR - proportion of at-bats resulting in a strikeout for right-handed pitchers
Step-by-step explanation:
The null hypothesis (H0) tries to show that no significant variation exists between variables or that a single variable is no different than its mean. While an alternative Hypothesis (Ha) attempt to prove that a new theory is true rather than the old one. That a variable is significantly different from the mean.
The null hypothesis for this case is that left-handed pitchers in a baseball league are not more likely to strike out batters than right-handed pitchers are. That is the proportion of at-bats resulting in a strikeout is significantly equal for both left-handed and right-handed pitchers.
H0: PL - PR = 0
The alternative hypothesis is that the proportion of at-bats resulting in a strikeout is significantly higher for left-handed pitchers
Ha: PL - PR > 0
PL - proportion of at-bats resulting in a strikeout for left-handed pitchers
PR - proportion of at-bats resulting in a strikeout for right-handed pitchers
