### Hypothesis Testing for Smartphone Carrier's Data Speeds#### Problem StatementThe display provided from technology available below results from using data for a smartphone carrier's data speeds at airports to test the claim that they are from a population having a mean less than 4.00 Mbps. Conduct the hypothesis test using these results. Use a 0.05 significance level. Identify the null and alternative hypotheses, test statistic, P-value, and state the final conclusion that addresses the original claim.#### Null and Alternative HypothesesAssuming all conditions for conducting a hypothesis test are met, what are the null and alternative hypotheses?- **Option A:** - Null Hypothesis (H₀): μ ≥ 4.00 Mbps - Alternative Hypothesis (H₁): μ < 4.00 Mbps- **Option B:** - Null Hypothesis (H₀): μ = 4.00 Mbps - Alternative Hypothesis (H₁): μ < 4.00 Mbps- **Option C:** - Null Hypothesis (H₀): μ ≥ 4.00 Mbps - Alternative Hypothesis (H₁): μ ≠ 4.00 Mbps- **Option D:** - Null Hypothesis (H₀): μ = 4.00 Mbps - Alternative Hypothesis (H₁): μ ≠ 4.00 Mbps- **Option E:** - Null Hypothesis (H₀): μ = 4.00 Mbps - Alternative Hypothesis (H₁): μ > 4.00 Mbps#### Identifying Test Statistics- **Round to two decimal places as needed.**#### Identifying the P-Value- **Round to three decimal places as needed.**#### Final ConclusionState the final conclusion that addresses the original claim:H₀: **There is** [__fill in__] **evidence to support the claim that the sample is from a population with a mean less than 4.00 Mbps.**---In this problem, you would typically choose the correct null and alternative hypotheses and then perform statistical analysis to find the test statistic and the P-value. Based on the P-value compared to the significance level (0.05), you would draw a conclusion to either reject the null hypothesis or fail to reject it. If rejected, you would have evidence to support the ### T-Test Result Display from Technology#### Variables- **Population Mean (µ)**: Less than 4.00- **Test Statistic (t)**: -3.825604- **P-value (p)**: 0.000185- **Sample Mean (x̄)**: 3.38- **Sample Standard Deviation (Sx)**: 1.145979- **Sample Size (n)**: 50#### Explanation of Results- **Population Mean (µ)**: The hypothesis test evaluates whether the true population mean is less than 4.00.- **Test Statistic (t)**: The calculated t-value is -3.825604, which indicates how many standard deviations the sample mean is from the hypothesized population mean.- **P-value (p)**: With a p-value of 0.000185, which is less than the significance level (commonly 0.05), the result is statistically significant, leading us to reject the null hypothesis.- **Sample Mean (x̄)**: The average value of the sample data is 3.38.- **Sample Standard Deviation (Sx)**: The variability or dispersion of the sample data points around the sample mean is 1.145979.- **Sample Size (n)**: The number of observations or data points in the sample is 50.This data helps in conducting a T-Test to infer if there is enough statistical evidence to say that the population mean is less than 4.0 based on the given sample data.

Online dating sites and mobile dating apps have become more popular over the years for American adults,according to the Pew Research Center. In 2013, 11% of adults in the US reported using online sites and mobileapps for dating. In a follow-up Pew Research poll in 2016, that percent jumped up to 15% of American adults.From the 2016 data, a hypothesis test was performed using a significance level of 0.01 and the results are shownin the output below. Based on this, can we conclude that the percentage of American adults who use online sitesor mobile apps for dating has increased since 2013? If not, what conclusion would be appropriate based on thesample data?
