Answer:
12.12ft
Step-by-step explanation:
14² = 7² + x²
x² = 14² - 7²
x² = 196 - 49
x² = 147
x = √147
x = 12.12ft
Ratio of orange:green = 2:1
If there are 4 green picks then there are 8 orange picks.
Total number of picks = 4 + 8 = 12
Answer: There are now 12 picks in total.
Answer:
Interval for t statistic = (-1.345, 1.345)
Step-by-step explanation:
given that a random sample of size 15 is selected from a normal population. The population standard deviation is unknown.
Since population std deviation is unknown and also sample size <30, we have to use t test only for testing of hypothesis
Given it is a two tailed test at 10% significance level.
Degree of freedom = 15-1 =14
t critical value for df 14 two tailed is
1.345
Hence our test statistic should lie between
(-1.345, 1.345)
Then null hypothesis is accepted
Other wise it is rejected.
