Answer:
Step-by-step explanation:
The null hypothesis is:
H0: μ(1995)=μ(2019)
The alternative hypothesis is:
H1: μ(1995)<μ(2019)
Because Roger wants to know if mean weight of 16-old males in 2019 is more than the mean weight of 16-old males in 1995 the test only uses one tail of the z-distribution. It is not a two-sided test because in that case the alternative hypothesis would be: μ(1995)≠μ(2019).
To know the p-value, we use the z-statistic, in this case 1.89 and the significance level. Because the problem does not specify it, we will search for the p-value at a 5% significance level and at a 1%.
For a z of 1.89 and 5% significance level, the p-value is: 0.9744
For a z of 1.89 and 1% significance level, the p-value is: 0.9719
For 3/9, the repeating decimal is .3
Answer:
Step-by-step explanation:
Amount by which the plant gre in one month = 9.5 - 8.75 = 0.75
Amount by which it will grow in x months = x * 0.75
The hegiht of the plant after 6 months = amount it will grow by in 6 months + current heigt = 0.75x + 8.75
Hence answer is
